has no son

قُلْ إِن كَانَ لِلرَّحْمَـٰنِ وَلَدٌ فَأَنَا۠ أَوَّلُ ٱلْعَـٰبِدِينَ

Say [Prophet], ‘If the Lord of Mercy [truly] had offspring I would be the first to worship [them], but-

وَأَنَّهُۥ تَعَـٰلَىٰ جَدُّ رَبِّنَا مَا ٱتَّخَذَ صَـٰحِبَةً وَلَا وَلَدًا

and that He––exalted be the glory of our Lord!––has neither spouse nor child.

لَمْ يَلِدْ وَلَمْ يُولَدْ

He begot no one nor was He begotten.
