The greatest of all the angels is Jibreel, upon whom be peace, who was described in the following report: "From ‘Abdullah ibn Mas‘ood (may Allah be pleased with him) who said: the Messenger of Allah (peace and blessings of Allah be upon him) saw Jibreel in his true form. He had six hundred wings, each of which covered the horizon. There fell from his wings jewels, pearls and rubies, only Allah knows about them." It was reported by Ahmad in al-Musnad, and Ibn Katheer said in al-Bidayah that its isnad (chain of narrators) is jayyid (good).
