Tafsir of Ad-Dhuha 93:9

Therefore, treat not the orphan with oppression. meaning, `just as you were an orphan and Allah sheltered you, then do not oppress the orphan.' In other words, `do not humiliate him, scorn him or despise him. Rather, you should be kind and gentle to him.' Qatadah said, "Be like a merciful father to the orphan.''
