سورة التوبة

The Messenger of Allah (peace be upon him and his family): Ibn Abbas (may Allah have mercy on him) said: When the blessed verse يا أَیُّهَا النَّبِیُّ جاهِدِ الْکُفَّارَ وَ الْمنافِقِینَ [O Prophet! strive hard against the unbelievers and the hypocrites] was revealed, the Messenger of Allah (peace be upon him and his family) said: "I shall certainly wage jihad against the unbelievers!" Following this statement, Jibra'il descended and said: "This jihad and fighting will be carried out by you or by Ali (peace be upon him)."

Imam Baqir (peace be upon him): جاهِدِ الْکُفَّارَ وَ الْمُنافِقِینَ [strive hard against the unbelievers and the hypocrites] — wage jihad by way of making the obligatory duties binding.

The Messenger of Allah (peace be upon him and his family): The debt of the Prophet (peace be upon him and his family), which was a promise amounting to eighty thousand dirhams — Ali (peace be upon him) paid them off. And among the debts he discharged on his behalf was the debt to Allah, which is greater, comprising the matters that Allah had made incumbent upon him. The Prophet passed away before discharging them, and he made a bequest to Ali (peace be upon him) to carry them out on his behalf. This is the very statement of Allah the Exalted where He said: يا أَیُّهَا النَّبِیُّ جاهِدِ الْکُفَّارَ وَ الْمنافِقِینَ [O Prophet! strive hard against the unbelievers and the hypocrites]. So the Prophet, during his life, waged jihad against the unbelievers and commanded Ali (peace be upon him) to wage jihad against the hypocrites after his passing. Thus Ali (peace be upon him) waged jihad against the Nakithin, the Qasitin and the Mariqin, and in this way he discharged the debt of the Messenger of Allah (peace be upon him and his family) owed to Allah.
