Mukhtasar Muslim

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said to me: O Abu Hurairah! (may Allah be pleased with him) People will keep asking you (about religious matters) until they say: Well, Allah is there, so who created Allah? He says that once I was sitting in the mosque when some Bedouins came and said: O Abu Hurairah! Allah is there, so who created Allah? Hearing this, Sayyiduna Abu Hurairah (may Allah be pleased with him) threw a handful of pebbles at them and said: Get up, get up! My friend, the Messenger of Allah (peace and blessings of Allah be upon him), spoke the truth.
