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."
Sahih al-Bukhari Book 65, Hadith 497
← Previous Hadith The Prophet (ﷺ) said, "Allah said: 'The son of Adam tells a lie against Me,, though he hasn't the right to do so. He abuses me though he hasn't the right to do so. As for his telling a lie against Me, it is his saying that I will not recreate him as I created him for the first time. In fact, the first creation was not easier for Me than new creation. As for his abusing Me, it is his saying that Allah has begotten children, while I am the One, the Self-Sufficient Master Whom all creatures need, I beget not, nor was I begotten, and there is none like unto Me."

Sahih al-Bukhari Book 65, Hadith 496 Next Hadith → I asked Ubai bin Ka`b regarding the two Muwwidhat (Surats of taking refuge with Allah). He said, "I asked the Prophet (ﷺ) about them, He said, 'These two Surats have been recited to me and I have recited them (and are present in the Qur'an).' So, we say as Allah's Messenger (ﷺ) said (i.e., they are part of the Qur'an."
