ذَٰلِكَ بِأَنَّهُۥ كَانَت تَّأۡتِيهِمۡ رُسُلُهُم بِٱلۡبَيِّنَٰتِ فَقَالُوٓاْ أَبَشَرٞ يَهۡدُونَنَا فَكَفَرُواْ وَتَوَلَّواْۖ وَّٱسۡتَغۡنَى ٱللَّهُۚ وَٱللَّهُ غَنِيٌّ حَمِيدٞ ٦
That is because their messengers used to come to them with clear evidences, but they said, "Shall human beings guide us?" and disbelieved and turned away. And Allāh dispensed [with them]; and Allāh is Free of need and Praiseworthy.
Translation: Saheeh International (English)
Each word's meaning and sound
That punishment which came on them, only came on them on account of the fact that their messengers used to bring clear evidence and glaring proof from Allah, but they said in denial of the fact that messengers could be from the human race: ‘Are human beings going to guide us to the truth?!’ So they disbelieved and turned away from having faith in them. But they did not harm Allah at all. Allah is in no need of their faith and obedience, because their obedience does not increase him in anything. Allah is Self-Sufficient and in no need of His servants. He is praiseworthy in His statements and actions.
