What did the Prophet Muhammad (saw) say when the Ansar declared their allegiance to him?
 Narrated Anas:                     On the day (of the battle) of the Trench, the Ansar were saying, "We are those who have sworn allegiance to Muhammad for Jihaid (for ever) as long as we live." The Prophet replied to them, "O Allah! There is no life except the life of the Hereafter. So honor the Ansar and emigrants with Your Generosity."
