It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him), during his final illness, came out with a band tied around his blessed head, ascended the pulpit, praised and glorified Allah, and said: "With regard to my life and my wealth, there is no one who has done more favor to me than Abu Bakr ibn Abi Quhafa (may Allah be pleased with him). If I were to take anyone from among mankind as a close friend (khalil), I would have taken Abu Bakr as my close friend, but the brotherhood of Islam is the best. Close every window opening into this mosque except the window of Abu Bakr (may Allah be pleased with him)."
