Abu Nu^aym reported in his book, Al-Hilyah:
**In the biography of ^Aliyy Ibn Abi Talib, he said that Nawf Ibn ^Abdullah entered the quarters of the Emirate in Kufah, that is, the house of ^Aliyy Ibn Abi Talib and said: “O Amir of the Believers, there are forty Jews at the door.” To this, ^Aliyy replied: “Let them in.” When they entered, they said to ^Aliyy: “Describe your Lord for us, the One Who is in the sky. How is He? How was He? When was He? On what is He?” ^Aliyy sat up and said: “You Jews, hear me out and you would not have to ask anyone else. My Lord, the Exalted, is al-'Awwal (i.e., the One Whose Existence is without a beginning). He is not from anything, nor mixed with anything, nor deluded about, nor a person that would be sought, nor is veiled, thus contained, nor did He exist after He had not been existing.” And he said: “Allah spoke to Moses without limbs or instruments or lips nor uvulas… He who claims that our God is limited, then he is ignorant about the Creator Who is worshipped.” **
Praise be to Allah. We clear Allah of all non-befitting attributes, and Allah knows best.
