Thabit narrates from Sayyiduna Anas (may Allah be pleased with him): The Messenger of Allah (peace and blessings be upon him) came to us, and there was no one present except me, my mother and my maternal aunt Sayyidah Umm Haram (may Allah be pleased with her). He (peace and blessings be upon him) said: "Stand up, so that I may lead you in prayer." He (peace and blessings be upon him) led us in prayer at a time other than an (appointed) prayer time. Someone asked Thabit (may Allah have mercy on him): Where did the Prophet (peace and blessings be upon him) make him stand? He replied: On his right side. When the Prophet (peace and blessings be upon him) completed the prayer, he supplicated for the household for every good of this world and the Hereafter. My mother said: O Messenger of Allah, supplicate to Allah for this little servant of yours as well. He (peace and blessings be upon him) supplicated for me, and the last supplication he (peace and blessings be upon him) made for me was: 'Allahumma akthir malahu wa waladahu wa barik lahu fihi' (O Allah, increase his wealth and his children, and bless him in it).
