"Verily, those who unjustly eat up the property of orphans" -A man would have an orphan in his care, and he would keep his food, drink and vessels separate. This caused hardship to the Muslims, so Allah, the Mighty and Sublime, revealed: "And they ask you concerning orphans. Say: The best thing is to work honestly in their property, and if you mix your affairs with theirs, then they are your brothers" (in religion), so it is permissible for you to mix with them.

"Avoid the seven sins that doom one to Hell." It was said: "O Messenger of Allah, what are they?" He said: "Associating others with Allah (Shirk), magic, killing a soul whom Allah has forbidden killing, except in cases dictated by Islamic law, consuming Riba, consuming the property of orphans, fleeing on the day of the march (to battlefield), and slandering chaste women who never even think of anything touching their chastity and are good believers."
