It is narrated from Hazrat Anas (may Allah be pleased with him) that once the Ansar gathered together and came to the Prophet (peace and blessings be upon him) and said, "How long will we keep drawing water from wells? Let us go to the Prophet (peace and blessings be upon him) so that he may supplicate to Allah for us to cause springs to flow from these mountains." When the Prophet (peace and blessings be upon him) saw them, he 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 said to one another, "Consider this an opportunity and ask for forgiveness for your sins." So they said, "O Messenger of Allah (peace and blessings be upon him)! Supplicate 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." They said, "O Messenger of Allah (peace and blessings be upon him)! What about our other offspring, are they not included among us?" The Prophet (peace and blessings be upon him) included them in the supplication as well. Then they mentioned their freed slaves, so the Prophet (peace and blessings be upon him) included them too.

The previous hadith is also narrated through this second chain of transmission.
