The Messenger of Allah (ﷺ) said to me : they (the people) till constantly ask you , Abu Huraira , (about different things pertaining to religion) the they would say : Well , there is Allah , but after all who created Allah ? He (Abu Huraira) narrated : Once we were in the mosque that some of the Bedouins came there and said : Well , there is Allah , but who created Allah ? He (the narrator) said : I took hold of the pebbles in my fist and flung at them and remarked : Stand up , stand up (go away) my friend (the Holy Prophet) told the truth.
