Refutation of polytheism and false beliefs

فَٱسْتَفْتِهِمْ أَلِرَبِّكَ ٱلْبَنَاتُ وَلَهُمُ ٱلْبَنُونَ

So inquire of them, [O Muḥammad], "Does your Lord have daughters while they have sons?

قُلْ إِن كَانَ لِلرَّحْمَـٰنِ وَلَدٌ فَأَنَا۠ أَوَّلُ ٱلْعَـٰبِدِينَ

Say, [O Muḥammad], "If the Most Merciful had a son, then I would be the first of [his] worshippers."
