Ali ibn Abi Talib

Beware! I called you (insistently) to fight these people night and day, secretly and openly and exhorted you to attack them before they attacked you, because by Allah, no people have been attacked in the hearts of their houses but they suffered disgrace; but you put it off to others and forsook it till destruction befell you and your cities were occupied.

When Amir al-mu'minin showed his intention to fight the Kharijites, he was told that they had crossed the bridge of Nahrawan and gone over to the other side. Amir al-mu'minin said: "Their falling place is on this side of the river. By Allah, not even ten of them will survive while from your side not even ten will be killed."

Ibrahim al-Taimi reported on the authority of his father: 'Ali b. Abu Talib (Allah be pleased with him) addressed us and said: He who thinks that we (the members of the Prophet's family) read anything else besides the Book of Allah and this Sahifa (and he said that Sahifa was tied to the scabbard of the sword) tells a lie. (This Sahifa) contains (problems) pertaining to the ages of the camels and (the recompense) of the injuries, and it also records the words of the Prophet (ﷺ): Medina is a sacred territory from 'Ayr to Thaur (it is most probably Uhud). He who innovates (an act or practice) or gives protection to an innovator, there is a curse of Allah and that of His angels and that of the whole humanity upon him. Allah will not accdpt from him (as a recompense) any obligatory act or supererogatory act, and the responsibility of the Muslims is a joint responsibility; even the lowest in rank can undertake the responsibility (on behalf of others), and he who claims anyone else as his father besides his own father or makes one his ally other than the one (who freed him), there is a curse of Allah. that of His angels and that of the wholemankind upon him. Allah will not accept the obligatory act of the supererogatery act (as a recompense) from him.
