It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: I heard the Messenger of Allah (peace and blessings be upon him) say: "I and the one who takes care of an orphan - whether the orphan is his own (relative) or someone else's - will be in Paradise (like this), and the one who strives to meet the needs of the widow and the poor is like one who fights in the way of Allah."
Only Muhammad bin al-Munkadir (may Allah have mercy on him) narrated this hadith from Umm Dharrah (may Allah have mercy on her), only Layth (may Allah have mercy on him) from Muhammad bin al-Munkadir (may Allah have mercy on him), and only Hafs (may Allah have mercy on him) from Layth (may Allah have mercy on him), while Sahl bin Uthman (may Allah have mercy on him) is alone in narrating it.
