Musannaf Ibn Abi Shaybah 38072 — The words of al-Hasan al-Basri

Hisham bin Urwah narrates from his father that he said: When you see a man doing a good deed, know that he has other good deeds as well, for a good deed points to a good deed. And when you see a man committing a sin, know that he has other sins as well, for a sin points to a sin.
