Sahih Bukhari Volume 7, Book 72, Hadith Number 837.

Narrated By Abu Zur’a : I entered a house in Medina with Abu Huraira, and he saw a man making pictures at the top of the house. Abu Huraira said, “I heard Allah’s Apostle saying that Allah said, ‘Who would be more unjust than the one who tries to create the like of My creatures? Let them create a grain: let them create a gnat.’ “Abu Huraira then asked for a water container and washed his arms up to his armpits. I said, “0 Abu I Huraira! Is this something you have heard I from Allah’s Apostle?” He said, “The limit for ablution is up to the place where the ornaments will reach on the Day of Resurrection.”
