Musannaf Ibn Abi Shaybah 34094 — Reports on Abu Bakr al-Siddiq

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) addressed the people and said: "Indeed, among the people the one who has done me the most favour in his companionship and his wealth is Abu Bakr. If I were to take anyone from among the people as a friend, I would take Abu Bakr as a friend, but with him there is the brotherhood and love of Islam. And let all the doors opening into the mosque be closed except the door of Abu Bakr."
