Mukhtasar Bukhari

Abu Huraira (may Allah be pleased with him) says: I heard the Prophet Muhammad (peace be upon him) say, "Allah Almighty says: Who is more unjust than the one who wishes to create like Me? (If he is such a creator,) then let him create a grain of wheat or let him create an ant." In another narration, it is added: "Let him produce the grain (i.e., the produce) and show it."
