It is narrated from Hazrat Amir that under the tree, the first to pledge allegiance was Abu Sinan Asadi Wahb. He came to the service of the Holy Prophet (peace and blessings be upon him) and said, "I pledge allegiance to you." The Holy Prophet (peace and blessings be upon him) asked, "On what matter do you pledge allegiance to me?" Abu Sinan said, "On that which is in your heart." The narrator says, so the Holy Prophet (peace and blessings be upon him) accepted his pledge. The narrator says, then another man came to the Holy Prophet (peace and blessings be upon him) and said, "On the matter upon which Abu Sinan pledged allegiance, I also pledge allegiance to you." So he too pledged allegiance to the Holy Prophet (peace and blessings be upon him). Then the rest of the people pledged allegiance to the Holy Prophet (peace and blessings be upon him).
