ibn Abbas · The Book of al-Bay'ah

"I pledged to the Messenger of Allah to be sincere toward ever Muslim."

"I came to the Messenger of Allah with my father Umayyah on the Day of the Conquest (of Makkah) and said: 'O Messenger of Allah, accept my father's pledge for emigration (Al-Hijrah).' The Messenger of Allah said: 'I will accept his pledge to fight in Jihad, for the emigration (Al-Hijrah) has ceased."'

a man asked the Prophet, when he had put his leg in the stirrup: "Which kind of Jihad is best?'" He said: " a word of truth spoken before an unjust rulers."
