Musannaf Ibn Abi Shaybah 8261 — A man praying with his hair braided

Zayd bin Wahb said: Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) entered the mosque and saw a man praying with his hair tied up. When he finished the prayer, Sayyiduna Abdullah said: "When you pray, do not braid your hair, for your hair prostrates along with you, and you receive a reward for every hair." The man said: "I fear that it will get dusty." Sayyiduna Abdullah said: "Its getting dusty is better for you."
