Al-Ashbaah (literally, "the skeletons"), in which Ali talked about the creation of the universe

(O Allāh) I stand witness that he who likens Thee with the separateness of the limbs or with the joining of the extremities of his body did not acquaint his innerself with knowledge about Thee, and his heart did not secure conviction to the effect that there is no partner for Thee. It is as though he has not heard the (wrongful) followers declaiming their false gods by saying “By Allāh, we were certainly in manifest error when we equalled you with the Lord of the worlds.” (Qur’ān, 26:97-98).
