Ibn Mas‘ūd (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "I saw Jibrīl at the Lote Tree and he had six hundred wings." He said: "I asked ‘Āsim about the wings, but he refused to tell me. Then some of his companions said to me: "A single wing covered the distance between the east and west."
