﴿ ذَٰلِكَ بِأَنَّهُۥ كَانَت تَّأْتِيهِمْ رُسُلُهُم بِٱلْبَيِّنَٰتِ فَقَالُوٓا۟ أَبَشَرٌۭ يَهْدُونَنَا فَكَفَرُوا۟ وَتَوَلَّوا۟ ۚ وَّٱسْتَغْنَى ٱللَّهُ ۚ وَٱللَّهُ غَنِىٌّ حَمِيدٌۭ ﴾

“this, because time and again there came unto them their apostles with all evidence of the truth, but they [always] replied, "Shall mere mortal men be our guides?" And so they. denied the truth and turned away. But God was not in need [of them]: for God is self-sufficient, ever to be praised.”

That chastisement in this world is because bi-annahu contains the pronoun of the matter their messengers used to bring them clear signs manifest proofs for the validity of faith but they said ‘Shall mere humans basharan is meant as generic be our guides?’ So they disbelieved and turned away from faith and God was independent without need of their faith. And God is Independent without need of His creatures Praised praiseworthy in His actions.
