Musannaf Ibn Abi Shayba 16:981

Abu Bakr narrated to us, he said: Ibn Fudayl narrated to us, from 'Umarah, from Abu Zur'ah, who said: I entered the house of Marwan with Abu Hurayrah, and he saw pictures in it. He said: I heard the Prophet, may Allah bless him and grant him peace, say: "Allah says: 'And who is more unjust than the one who goes to create a creation like My creation? So let them create a grain, and let them create an atom, and let them create a barleycorn.'" He said: Then he called for water for ablution and performed ablution.
