Jihadi ni wajibu kwa Waislamu bila ubaguzi kati ya wacha Mungu na wasiomcha, au kati ya walio wakweli katika imani na mnafiki. Aya za jihadi zilipokuja, zilikuja kwa ujumla. Matini zinapokuja kwa ujumla, hubaki za kujumuisha mpaka pale isipokuwepo matini maalum inayozibainisha; hakuja matini inayobainisha jihadi kwa baadhi ya Waislamu na si kwa wengine, hivyo matini zinabaki za ujumla. Kwa msingi huo, inaruhusiwa kuwaandikisha wanafiki, wasiomcha na yule anayepigana kwa hasira katika jeshi la Kiislamu. Kuhusu ruhusa kwao kuwepo pamoja na Waumini walio wakweli katika kupigana na maadui, na katika jeshi la Kiislamu, hii inatokana na ujumla wa aya za jihadi. Pia ni kwa sababu Mtume ﷺ alimtumia kiongozi wa wanafiki, Abdullah bin ‘Ubayy, katika jihadi; alihudhuria baadhi ya vita na mashauriano ya kijeshi pamoja naye ﷺ siku ya Uhud kabla ya vita. Mwenyezi Mungu (SWT) alimkemea Mtume ﷺ alipowaruhusu wanafiki kubaki nyuma na kutopigana huko Tabuk. Mwenyezi Mungu (SWT) amesema:

Jihad is obligatory upon Muslims without distinction between the pious and the impious, or the sincere in belief and the hypocrite. When the ayaat of jihad came, they came in general. When the texts come in general, they remain general as long as there is no specific text specifying them; there came no text specifying jihad for some Muslims and not others, so the texts remain general. Accordingly it is allowed to enrol hypocrites, the impious and the one who fights due to anger in the Islamic army. As for the permission for them to be present with the sincere believers in fighting the enemies, and the Islamic army, this is due to the generality of the ayaat of jihad. This is also because the Messenger (saw) took the assistance of the head of the hypocrites, Abdullah bin ‘Ubayy, in jihad; he attended some battles and the military consultations with him (saw) on the day of Uhud before the battle. Allah (swt) reproved the Messenger when he permitted the hypocrites to stay behind the fighting in Tabuk. Allah (swt) said:

Kuhusu waovu, hili linatokana na ujumla wa aya, na kutokana na aliyosimulia Sa'id bin Al-Musayyab kutoka kwa Abu Hurairah (ra) ambaye alisema:

As for the impious, this is due to the generality of the ayat and due to what Said bin Musayyab narrated from Abu Hurairah (ra) who said:

Hii pia ni kwa sababu jihadi ni miongoni mwa wajibu unaotekelezwa na Khalifah. Akiacha kuitekeleza dhidi ya makafiri, na yeye ni Muislamu, hilo litakuwa ni kuacha kutekeleza hukumu ya Allah (SWT), jambo ambalo ni haramu na halikubaliwi. Kwa hiyo ni wajibu kutekeleza jihadi dhidi ya makafiri kama inavyotekelezwa dhidi ya wacha Mungu, sawa kabisa.

This is also because jihad is one of the obligations implemented by the Khalifah. If he does not implement it upon upon the impious, who is a Muslim, this would be leaving the implementation of a rule of Allah (swt) which is haram and not permitted. Accordingly it is obliged to implement jihad upon the impious as it is implemented upon the pious equally
