Hazrat Abu Saeed Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) addressed the people and said: Indeed, among the people, the one who has done the greatest favor to me in terms of love and wealth is Abu Bakr. If I were to take anyone as a close friend from among the people, I would have taken Abu Bakr as a close friend, but (between us) is only Islamic brotherhood and love. And all the doors opening into the mosque should be closed except the door of Abu Bakr.
