Musannaf Ibn Abi Shaybah 38218 — Sayings of Ikrimah

Hassan bin Atiyyah said: Once a man was riding on a donkey when it suddenly stumbled with him, and he said, "May you perish!" The angel on the right side said, "This is no good deed that I should write it," and the angel on the left side said, "What evil deed is this that I should write it?" Then the angel on the left side was called: "Whatever statement the right one leaves, write it down."
