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."
The Prophet (may Allah's peace and blessings be upon him) saw Jibrīl in the highest part of Paradise, and he had six hundred wings. The narrator asked ‘Āsim ibn Abu Bahdalah about the appearance of these wings, but he did not inform him, so some of his companions informed him that owing to their huge size, each wing filled the distance between the east and west. This is also mentioned in other authentic Hadīths: "Due to the enormity of his creation, he filled what is between the east and the west.”
