They have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim]. Do you say about Allah that which you do not know?

قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًا سُبْحَٰنَهُۥ هُوَ ٱلْغَنِىُّ لَهُۥ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ إِنْ عِندَكُم مِّن سُلْطَٰنٍۭ بِهَٰذَآ أَتَقُولُونَ عَلَى ٱللَّهِ مَا لَا تَعْلَمُونَThey have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim].
