Muhammad bin Sirin, may Allah have mercy on him, says: I was with Sayyiduna Abu Hurairah, may Allah be pleased with him, when a man asked him a question. I do not know what that question was. In response, Sayyiduna Abu Hurairah, may Allah be pleased with him, said: «اللّٰہُ أَکْبَرُ» Two people have already asked about this, and this is the third. I heard the Messenger of Allah, peace and blessings be upon him, say: "Indeed, people will continue to ask questions, until they even ask: 'Allah Almighty created the creation, but who created Him?'"
