Musannaf Ibn Abi Shaybah 36104 — What I have memorised on al-Yarmuk

Suwayd bin Ghafalah said: We returned from the Battle of Yarmuk and Sayyiduna Umar (may Allah be pleased with him) came to receive us. At that time we were wearing garments of silk on our bodies. Sayyiduna Umar ordered the people to throw stones at us. We said: "Who knows what news has reached him about us?" Then we took off the silk garments and said: "He has disliked this appearance of ours." Then when we went to him, he welcomed us and said: "Earlier you came in the appearance of the polytheists, and Allah Almighty did not approve of silk for those before you either."
