Surah Az-Zukhruf — Ayah 82

أَمْ يَحْسَبُونَ أَنَّا لَا نَسْمَعُ سِرَّهُمْ وَنَجْوَىٰهُم ۚ بَلَىٰ وَرُسُلُنَا لَدَيْهِمْ يَكْتُبُونَ

Or do they think that We hear not their secrets and their private conversations? Yes, [We do], and Our messengers are with them recording.

قُلْ إِن كَانَ لِلرَّحْمَـٰنِ وَلَدٌ فَأَنَا۠ أَوَّلُ ٱلْعَـٰبِدِينَ

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

فَذَرْهُمْ يَخُوضُوا۟ وَيَلْعَبُوا۟ حَتَّىٰ يُلَـٰقُوا۟ يَوْمَهُمُ ٱلَّذِى يُوعَدُونَ

So leave them to converse vainly and amuse themselves until they meet their Day which they are promised.

وَهُوَ ٱلَّذِى فِى ٱلسَّمَآءِ إِلَـٰهٌ وَفِى ٱلْأَرْضِ إِلَـٰهٌ ۚ وَهُوَ ٱلْحَكِيمُ ٱلْعَلِيمُ

And it is Allah who is [the only] deity in the heaven, and on the earth [the only] deity. And He is the Wise, the Knowing.
