The Army has two sections: the reserve section, which is all those Muslims who are capable of carrying arms, and the section of regular soldiers, who get salaries from the State budget in the same manner as the civil servants.

Its evidence is the evidence of the obligation of Jihad, since every Muslim is obligated with Jihad and its training and accordingly all of the Muslims are a reserve army since Jihad is obligatory upon them. As for making a section of them to be full-time regular soldiers, its evidence is the rule.

. )ما لا يتم الواجب إلا به فهو واجب( .

“That, without which the obligation cannot be accomplished, is itself an obligation”,

since the carrying out of Jihad consistently, along with the defence of the Islamic lands and protecting the honour of the Muslims from the disbelievers cannot be done except with a permanent army. Therefore, it is obligatory upon the leader to establish a permanent army.

As for setting a salary for those soldiers in the same manner as the civil servants, with respect to the non-Muslims, this is clear since they are not required to fight against disbelievers, but if they undertake Jihad, it is accepted from them, at which time it is permitted to give them money as well as to give them a share from the portion of booty which is intended to bring the hearts closer to Islam – due to what is narrated by Al-Zuhri.

. » أَسْهَمَ لِقَوْمٍ مِنْ الْيَ هُودِ قَاتَ لُوا مَعَه أَنَّ النَّبِيَّ « .

“That the Messenger of Allah (pbuh) gave a portion to some people among the Jews who fought along with him” (reported by Al-Tirmidhi and it is from the Maraseel of Al-Zuhri, and Ibn Qudamah used it as an evidence in Al-Mugni). Also, it is narrated that.

. ي وَْمَ حُنَ يْنٍ وَهُوَ عَلَى شِرْكِهِ، فَأَسْهَمَ أَنَّ صَفْوَانَ بْنَ أُمَيَّةَ خَرَجَ مَعَ النَّبِيِّ « » لَهُ، وَأَعْطَاهُ مِنَ الغَنَائِمِ مَعَ المُؤَلَّفَةِ قُ لُوب هُُمْ .
