It is narrated from Hazrat Anas (may Allah be pleased with him) that once some fields were distributed among the Ansar. They gathered together and came to the Prophet (peace and blessings be upon him) with a request that they be allowed to take water from a running canal, and they would pay its rent. The Prophet (peace and blessings be upon him) said, "Welcome, O Ansar! By Allah! Today, whatever you ask of me, I will give you, and whatever I ask Allah for you, Allah will surely grant it to me." Hearing this, they began to say to each other, "Take advantage of this opportunity and ask for the forgiveness of your sins." So they said, "O Messenger of Allah (peace and blessings be upon him)! Pray to Allah for our forgiveness." The Prophet (peace and blessings be upon him) said, "O Allah! Forgive the Ansar, the children of the Ansar, and the children of the children of the Ansar."
