Abdullah bin Shaqiq reported,

I said to Abu Dharr, "If only you had seen the Messenger of Allah ﷺ, you would have asked him."He said, "What would you have asked him?"I replied, "I would have asked him whether he saw his Lord ."Abu Dharr said, "I did indeed ask him, and he said, 'I saw a light. How could I see Him?'"Affan said, "It has reached me from Ibn Hisham, meaning Muaz, that he narrated it from his father just as Hammam said, 'I have indeed seen Him.'"
