Volume 4, Book 52, Number 208:
Narrated Anas:
On the day (of the battle) of the Trench, the Ansar were saying, “We are those who have sworn al –
legiance to Muhammad for Jihaid (for ever) as long as we live.” The Prophet replied to them, “O Al –
lah! There is no life except the life of the Hereafter. So honor the Ansar and emigrants with Your
Generosity.”
And Narrated Mujashi: My brother and I came to the Prophet and I requested him to take the
pledge of allegiance from us for migration. He said, “Migration has passed away with its people.” I
asked, “For what will you take the pledge of allegiance from us then?” He said, “I will take (the
pledge) for Islam and Jihad.”
