Musannaf Ibn Abi Shaybah 8054 — Those who disliked taking pebbles out

Nufay' Abu Dawud said: I went out of the mosque with Sayyiduna Ibn Abbas (may Allah be pleased with them both). I took off my khuffs (leather socks), and he heard the sound of a pebble falling out. At this he said: "Put this pebble back, otherwise it will dispute with you on the Day of Resurrection."
