Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah ta'ala: "Allāh-uṣ-Ṣamad (The Self-Sufficient Master, Whom all creatures need, He neither eats nor drinks) ." (V.112:2)
Narrated Abu Huraira:
Allah's Messenger (ﷺ) said, "Allah said:-- 'The son of Adam tells a lie against Me and he hasn't the right to do so; and he abuses me and he hasn't the right to do so. His telling a lie against Me is his saying that I will not recreate him as I created him for the first time; and his abusing Me is his saying that Allah has begotten children, while I am the self-sufficient Master, Whom all creatures need, Who begets not nor was He begotten, and there is none like unto Me."
