ذَٰلِكَ بِأَنَّهُۥ كَانَت تَّأْتِيهِمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ فَقَالُوٓا۟ أَبَشَرٌۭ يَهْدُونَنَا فَكَفَرُوا۟ وَتَوَلَّوا۟ ۚ وَّٱسْتَغْنَى ٱللَّهُ ۚ وَٱللَّهُ غَنِىٌّ حَمِيدٌۭ
That was because their messengers (from Allah) kept coming unto them with clear proofs (of Allah's Sovereignty), but they said: Shall mere mortals guide us? So they disbelieved and turned away, and Allah was independent (of them). Allah is Absolute, Owner of Praise.
