Abu Hurairah reported,

The Prophet ﷺ reported that Allah said, "The son of Adam 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. As for his calling Me a liar, it is his saying, 'He will never bring me back as He first created me,' yet the original creation is no harder for Me than bringing him back. As for his insulting Me, it is his saying, 'Allah has taken a son,' while I am the One, the Eternal Refuge. I have not begotten, nor was I begotten, and there is none equal to Me."

عن أبي هريرة

عن النبي ﷺ قال: قال الله: كذبني ابن آدم ولم يكن له ذلك، وشتمني ولم يكن له ذلك، فأما تكذيبه إياي فقوله: لن يعيدني كما بدأني، وليس أول الخلق بأهون علي من إعادته، وأما شتمه إياي فقوله: اتخذ الله ولدا، وأنا الأحد الصمد، لم ألد ولم أولد، ولم يكن لي كفؤا أحد.
