What did Prophet Muhammad (saw) see when we read the words of Allah: "Certainly he saw of the greatest signs of Allah" (al-Qur'an, liii. 18)?
 Zirr b. Hubaish narrated it on the authority of 'Abdullah (that the words of Allah):                     " Certainly he saw of the greatest signs of Allah" (al-Qur'an, liii. 18) imply that he saw Gabriel in his (original) form and he had six hundred wings.
