Abu Hurairah reported,

The Messenger of Allah ﷺ said that Allah said, "My servant has called Me a liar, though he had no right to do so, and he has insulted Me, though he had no right to do so. His calling Me a liar is his saying that I will never bring him back as I first created him. And his insulting Me is his saying that Allah has taken a son, while I am the Eternal, who neither begets nor was begotten, and there is none comparable to Me."

وقال رسول الله ﷺ قال الله عز وجل كذبني عبدي ولم يكن له ذلك وشتمني ولم يكن له ذلك تكذيبه إياي أن يقول فلن يعيدنا كما بدأنا وأما شتمه إياي يقول اتخذ الله ولدا وأنا الصمد الذي لم ألد ولم أولد ولم يكن لي كفوا أحد
