Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh.
In the Name of Allah, Most Gracious, Most Merciful.
All praise and thanks are due to Allah, and peace and blessings be upon His Messenger.
Dear questioner, we would like to thank you for the great confidence you place in us, and we implore Allah Almighty to help us serve His cause and render our work for His Sake.
First, we would like to state that Islam does not call for violence; rather it abhors all forms of violence and terrorism, whether against Muslims or non-Muslims. Islam, moreover, calls for peace, cooperation, and maintaining justice, and provides for the happiness and welfare of humanity as a whole. This fact is declared in the Qur'an when Allah says: "Allah commands justice, the doing of good, and liberality to kith and kin, and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that ye may receive admonition." (An-Nahl: 90)
Islam makes it obligatory upon Muslims to stand by the oppressed regardless of their race, color, religion or affiliation and say NO to the oppressor and ask him to respond to the voice of reason and justice.
Jihad is not restricted to fighting aggressive forces. Rather, there are various kinds that most of people are not aware of. For example, striving against the evil desires of the soul is a kind of jihad that every Muslim should carry out.
For more elaboration on the point, we cite the following fatwa issued by Sheikh M. S. Al-Munajjid, a prominent Saudi Islamic lecturer and author:
�First, jihad is of various kinds, some of which are obligatory upon everyone who is accountable, and some are obligatory upon the community as a whole, i.e., if some people undertake them then the rest are relieved of the obligation. And some kinds of jihad are mustahabb (recommended).
Jihad an-nafs (jihad against one�s self) and jihad ash-Shaytan (jihad against Satan) are obligatory upon everyone who is accountable. Jihad against the munafiqin (hypocrites), kuffar (disbelievers) and leaders of oppression and innovation is obligatory upon the community as a whole. Physical jihad (i.e., fighting) against the kuffar may become an individual obligation upon everyone who is able to do it in certain circumstances, which will be described below.
Ibn al-Qayyim (may Allah have mercy on him) said: Once this is understood, then jihad is of four kinds: jihad an-nafs (jihad against one�s self), jihad ash-Shaytan (jihad against Satan), jihad against the kuffar and jihad against the hypocrites.
1. Jihad an-nafs (jihad against one�s self) is of four kinds:
a. Striving to learn the teachings of Islam without which one cannot attain success and happiness in this world or in the Hereafter. If this is missing, then one is doomed to misery in this world and in the Hereafter.
b. Striving to make oneself act in accordance with what one has learned. Simply knowing without acting, even though it may not cause any harm, is not going to bring any benefit.
c. Striving to call others to Islam, teaching those who do not know about it. Otherwise one will be one of those who conceal the guidance and teaching that Allah has revealed, and it will not benefit him or save him from the punishment of Allah.
d. Striving to bear patiently the difficulties involved in calling people to Allah and the insults of people, bearing all that for the sake of Allah.
If a person achieves all these four levels, then he will be one of the rabbaniyyin (learned men of religion who practice what they know and also preach to others. [see Al `Imran: 79]). The salaf (righteous predecesors) were agreed that the scholar does not deserve to be called a rabbani unless he knows the truth, acts in accordance with it, and teaches it to others. Whoever teaches, acts in accordance with his knowledge, and has knowledge will be called great in the kingdom of heaven.
2.Jihad ash-Shaytan (jihad against Satan) is of two types:
a. Warding off the doubts that Satan stirs up to undermine faith.
b. Striving against Satan to ward off the corrupt desires that he provokes.
The first jihad is followed by certainty of faith, and the second is followed by patience. Allah says: �And We made from among them [Children of Israel], leaders, giving guidance under Our Command, when they were patient and used to believe with certainty in Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.)� (As-Sajdah: 24)
Allah tells us that leadership in religion is attained through patience and certainty of faith. Patience wards off desires and certainty wards off doubts.
3. Jihad against the munafiqin (hypocrites) and kuffar (disbelievers) is of four kinds: with the heart, the tongue, one�s wealth and oneself. Jihad against the disbelievers is more along the lines of physical fighting, whereas jihad against the hypocrites is more along the lines of using words and ideas.
4. Jihad against the leaders of oppression and innovation is of three kinds: jihad with one's hand (i.e., physical jihad, fighting) if one is able. If that is not possible, then it should be with one's tongue (i.e., by speaking out). If that is not possible, then it should be with one's heart (i.e., by hating the evil and feeling that it is wrong).
These are the thirteen types of jihad, and �Whoever dies without having fought or having resolved to fight has died following one of the branches of hypocrisy.� (Reported by Muslim).
(Zad al-Ma`ad, 3/9-11)
Sheikh `Abd al-�Aziz ibn Baz (may Allah have mercy on him) said:
Jihad is of various kinds, with one�s self, one's wealth, by making du`a�, by teaching and guiding, by helping to do good in any way. The greatest form of jihad is jihad with one�s self (i.e., going oneself and fighting), followed by jihad with one's wealth, jihad by speaking out and guiding others. Da`wah is also part of jihad. But going out oneself to fight in jihad is the highest form. (Fatawa ash-Sheikh Ibn Baz, 7/334, 335)
Second, the idea of waging physical jihad against the disbelievers went through a number of stages, depending on the state in which the Muslim Ummah was. Ibn al-Qayyim (may Allah have mercy on him) said:
The first thing which his Lord revealed to him [Prophet Muhammad (peace and blessings be upon him)] was to read in the name of his Lord Who had created. That was the beginning of his Prophethood, when Allah commanded him to recite to himself but He did not yet command him to convey that. Then He revealed the words:
�O you (Muhammad) enveloped in garments! Arise and warn!� (Al-Muddaththir: 1-2)
So he became a Prophet with the word �Iqra� (Read!) and he became a Messenger with the words, �O you (Muhammad) enveloped in garments�� Then Allah commanded him to warn his closest kinsmen, then to warn his people, then to warn the Arabs around them, then to warn all the Arabs, then to warn all of mankind. He continued to call them for over ten years from the beginning of his Prophethood, without fighting or imposing the jizyah; he was commanded to refrain, to be patient and to be forbearing.
Then permission was given to him to migrate, and permission was given to him to fight.
Then he was commanded to fight those who fought him, and to refrain from fighting those who left him alone and did not fight him.
Then Allah commanded him to fight the disbelievers so that the religion would all be for Allah.
After jihad was enjoined upon him, the disbelievers then fell into three categories: those with whom there was a truce or peace treaty; those with whom he was at war; and those who lived under the rule and protection of the Islamic state. (Zad al-Ma`ad, 3/159)
Third The ruling on physical jihad against the disbelievers is that this is an obligation on the community as a whole (fard kafayah).
Ibn Qudamah said: �Jihad is an obligation upon the community; if some people undertake it, the rest are relieved of the obligation.�
What fard kafayah means is that if it is not undertaken by enough people, then all the people are guilty of sin, but if enough people undertake it, the rest will be relieved of blame. Initially the command is addressed to all of them, as in the case of an individual obligation (fard �ayn), but then in the case of fard kafayah the obligation is dropped if enough of the people undertake to do it, unlike the case with fard �ayn where the obligation is not dropped if someone else does it. Jihad is a fard kafayah according to the majority of scholars.� (Al-Mughni, 9/163)
Sheikh �Abd al-`Aziz ibn Baz said: �We have previously explained on more than one occasion that jihad is fard kafayah, not fard �ayn. All Muslims are enjoined to support their brothers with their selves (i.e., physically, by joining them), or with money, weapons, da`wah and advice. If enough of them go out (to fight), the rest are freed from sin; but if none of them do that, then all of them are sinners.
The Muslims in Saudi Arabia, Africa, North Africa and elsewhere are obliged to do their utmost, and if there is a Jihad in one country, the surrounding countries should hasten to help them, the closest then the next closest. If one or two states, or three or more, manage to fulfill the obligation, then the rest are freed of responsibility. They deserve to be supported, and it is obligatory to help them against their enemies because they are oppressed. Allah has enjoined jihad upon all Muslims, and they must fight against the enemies of Allah until their brothers are victorious. If they fail to do that, then they are sinners; but if sufficient people undertake to do that, then the rest are absolved of sin.� (Fatawa ash-Shaykh Ibn Baz, 7/335)
Fourth: Physical jihad against the disbelievers becomes obligatory in four cases, which are:
1. When the Muslim is present in a jihad situation.
2. When the enemy has come and attacked a Muslim land
3. When the ruler mobilizes the people, they must respond.
4. When a person is needed and no one else can do the task except him.
Sheikh Ibn `Uthaymin said:
Jihad is obligatory and becomes fard `ayn if a person is present where fighting is going on. This is the first of the situations in which jihad becomes an individual obligation, because Allah says: �O you who believe! When you meet those who disbelieve, in a battlefield, never turn your backs to them. And whoever turns his back to them on such a day � unless it be a stratagem of war, or to retreat to a troop (of his own), � he indeed has drawn upon himself wrath from Allah. And his abode is Hell, and worst indeed is that destination!� (Al-Anfal: 16)
The Prophet (peace and blessings be upon him) said that running away on the day when the army is advancing is one of the sins that doom a person to Hell. He said: �Avoid the seven sins that doom a person to Hell�� among which he mentioned running away on the day when the army is advancing. But Allah has made exceptions in two cases:
1. When it is a military maneuver, in the sense that he is leaving to bring reinforcements.
2. When he is going to join another group, when he has been told that there is a group of Muslims elsewhere who are about to be defeated, so he goes to join them in order to strengthen their numbers. This is subject to the condition that there is no risk to the group he is in; if there is a risk to the group that he is in, then it is not permissible for him to go to the other group. In this case (jihad) is an individual obligation upon him (fard `ayn) and it is not permissible for him to leave.
The second situation (in which jihad becomes an individual obligation) is when a city is besieged by the enemy. Then he has to fight to defend the city because there is no alternative but to defend it. For if the enemy is going to prevent people from leaving the city or entering it, and prevent provisions from reaching it, and other things which are well known, then in this case the people of the city are obliged to fight in order to defend their city.
The third situation is when the leader tells the people to mobilize. The Muslim ruler is the highest authority in the state, but he need not necessarily be the leader of all the Muslims, because there has been no leader of all the Muslims (caliph or khalifah) for a long time. The Prophet (peace and blessings be upon him) said: �Listen and obey, even if you are ruled by an Abyssinian slave.� So if a man becomes a leader, then his word is to be heeded and his commands are to obeyed. (Ash-Sharh al-Mumti`, 8/10-12).�
