Al-Risala adalah karya Imam Syafi'i:
Written in the second Islamic century by al-Imam al-Shafi’i (d. 204AH/820AD), the founder of one of the four Sunni schools of law. This important work gives the fundamental principles of Islamic jurisprudence and its influence continues to the present day. During the early years of the spread of Islam, the exponents of Islamic legal doctrine were faced with the problems raised by ruling and administering a diverse and rapidly growing empire. In Medina and Kufa, as well as other cities of early Muslim rule, schools of law had to be developed, but it took the genius of Muhammad b. Idris al-Shafi’i, born in the year 150AH/767AD, to establish the principles by which the various legal doctrines could be synthesised into a coherent system. In the Risala, which laid down the basis for such a synthesis, al-Shafi’i established the overriding authority, next only to the Qur’an, of the Sunna or example of the Prophet Muhammad as transmitted in the traditions.
Berikut adalah penjelasan Imam Syafi'i dalam karyanya Al-Risala mengenai status jihad yang berupa kewajiban umat islam secara kolektif (fard kifayah):
[Shafi'i replied]: God has imposed the [duty of] jihad as laid down in His Book and uttered by His Prophet's tongue. He stressed the calling [of men to fulfil] the jihad [duty] as follows:
God has bought from the believers their selves and their possessions against [the gift of] Paradise. They fight in the way of God; they kill, and are killed; that is a promise binding upon God in the Torah and Gospel and the Quran; and who fulfils his covenant better than God? So rejoice in the bargain you have made with Him. That is the mighty triumph [Q. IX, 112].
And He said:
Fight the polytheists totally as they fight you totally; and know that God is with the godfearing [Q. IX, 36].
And He said:
Slay the polytheists wherever you find them, and take them, and confine them, and lie in ambush for them everywhere. But if they repent and perform the prayer and pay the zakat, then set them free. God is All-forgiving, All-compassionate [Q. IX, 5].
And He said:
Fight those who do not believe in God nor the Last Day, who do not forbid what God and His Apostle have made forbidden, and who do not practice the religion of truth, of those who have been given the Book, until they pay the jizya out of hand and have been humbled [Q. IX, 29].
'Abd al-Aziz b. Muhammad al-Darawardi told us from Muhammad b. 'Amr b. 'Alqama from Abu Salama [b. 'Abd al-Rahman] from Abu Hurayra, who said that the Apostle of God said:
I shall continue to fight the unbelievers until they say: 'There is no god but God,' if they make this pronouncement they shall be secured their blood and property, unless taken for its price, and their reward shall be given by God.
And God, glorified be His praise, said:
O believers, what is the matter with you, that when it is said to you: 'Go forth in the way of God,' you sink down to the ground? Are you so content with this present life as to neglect the Hereafter? The enjoyment of this life is little in comparison with the Hereafter. If you do not go forth, He will inflict upon you a painful punishment, and instead of you He will substitute another people; and you will not hurt Him at all, for God is powerful over everything [Q. IX, 38-39].
And He said:
Go forth, light and heavy! Struggle in God's way with your possessions and yourselves! That is better for you, did you but know [Q. IX, 41].
[Shafi'i] said: These communications mean that the jihad, and rising up in arms in particular, is obligatory for all able-bodied [believers], exempting no one, just as prayer, pilgrimage, and [payment of] alms are performed, and no person is permitted to perform the duty of another, since performance by no one will not fulfil the duty for another. They may also mean that the duty of [jihad] is a collective (kifaya) duty different from that of prayer: Those who perform it in the war against the polytheist will fulfil the duty and receive the supererogetory merit, thereby preventing those who have stayed behind from falling into error.
But God has not put the two [categories of men] on an equal footing, for He said:
Such believers who sit at home-unless they have an injury-are not the equals of those who fight in the path of God with their possessions and their selves. God has given precedence to those who fight with their possessions and their selves over those who sit at home. God has promised the best of things to both, and He has preferred those who fight over those who sit at home by [granting them] a mighty reward [Q. IV, 97].
The literal meaning of this communication is that the duty is obligatory on all men.
He asked: Where is the proof for your opinion that if some people perform the duty, the others would be relieved of punishment?
[Shafi'i said]: It is the communication [that I have just cited].
He asked: In what part of it?
[Shafi'i] replied: God said: "Yet to each God has promised the best of things." Thus God has promised "the best of things" for those who stayed behind and could not go to the jihad, although he clearly specified his preference for those who went to the jihad over those who stayed at home. If those who stayed at home were in error, while others were fighting, they would be committing a sin, unless God forgives them, rather than receiving "the best of things."
He asked: Is there any other [proof]?
[Shafi'i] replied: Yes, God said: It is not for the believers to go forth all together, but why should not a party of every section of them go forth, to become learned in religion, and to warn their people when they return to them, perhaps they will beware [Q. IX, 123].
[When] the Apostle went to battle he was accompanied by some of his companions while others stayed at home; for Ali b. Abi Talib stayed at home during the battle of Tabuk. Nor did God ordain that all Muslims were under obligation to go to battle, for He said: "Why should not a party of every section of them go forth?" So He made it known that going into battle was obligatory on some, not on all, [just] as knowledge of the law is not obligatory on all but on some, save the fundamental duties which should be known to all men. But God knows best.
Shafi'i said: In like manner are other duties, the fulfilment of which is intended to be collective; whenever they are performed by some Muslims collectively, those who do not perform them will not fall in error. If all men failed to perform the duty so that no able-bodied man went forth to battle, all, I am afraid, would fall into error (although I am certain this would never happen) in accordance with [God's] saying: If you do not go forth, He will inflict upon you a painful punishment [Q. IX, 39].
He asked: What is the meaning [of this communication]?
[Shafi'i] replied: It means that it is not permissible that all men should fail to "go forth"; but that if some go forth, so that a sufficient number fulfils [the collective duty], the others do not fall into error, because the going forth by some would fulfil the [duty of] 'going forth'.
He asked: are there examples other than the jihad?
[Shafi'i] replied: [Yes, such as] the funeral and burial prayers, the performance of which should not be neglected; but men are not all under the obligation to attend to their performance, for those who perform them will relieve those who do not from falling into error
So far as I have been informed, the Muslims have continued to act as I have stated, from the time of the Prophet to the present.
Only a few men must know the law, attend the funeral service, perform the jihad and respond to greeting, while others are exempt. So those who know the law, perform the jihad
, attend the funeral service, and respond to a greeting will be rewarded, while others do not fall into error since a sufficient number fulfil the [collective] duty
