It is narrated from Umm al-Mu’minin Sayyida Aisha Siddiqa (may Allah be pleased with her) that on the day when the illness of the Messenger of Allah (peace and blessings be upon him) began, he (peace and blessings be upon him) came to me. I said:“Oh, my head!”He (peace and blessings be upon him) said:“I wish that this (death) would happen to you during my lifetime, so that I could prepare you for the Hereafter and bury you myself.”So I said, with a sense of jealousy:“It seems to me as if you (peace and blessings be upon him) would spend the night with another of your wives on that very day.”He (peace and blessings be upon him) said:“Oh, my head! Call your father and brother to me, so that I may write a document in favor of Abu Bakr (may Allah be pleased with him). I fear that someone else may say or someone may wish that he is more deserving (of the Caliphate of Prophethood). Allah Almighty and the believers will not be pleased with anyone other than Abu Bakr (may Allah be pleased with him).”
