The Messenger of Allah (ﷺ) got some prisoners of war (slaves). I my sister and Fatimah, daughter of the prophet (ﷺ), went to the prophet (ﷺ). We complained to him about our condition, and asked him to command for giving us some prisoners (slaves). The Messenger of Allah (ﷺ) said; The orphans of Badr came before you (and took the slaves). The transmitter then mentioned the story of glorifying Allah after every prayer. He did not mention sleeping.
