ذَٰلِكَ بِأَنَّهُۥ كَانَت تَّأۡتِيهِمۡ رُسُلُهُم بِٱلۡبَيِّنَٰتِ فَقَالُوٓاْ أَبَشَرٌ يَهۡدُونَنَا فَكَفَرُواْ وَتَوَلَّواْ ۚ وَّٱسۡتَغۡنَى ٱللَّهُ ۚ وَٱللَّهُ غَنِىٌّ حَمِيدٌ
That was because there came to them messengers with Clear Signs, but they said: "Shall (mere) human beings direct us?" So they rejected (the Message) and turned away. But Allah can do without (them): and Allah is free of all needs, worthy of all praise.<br/>
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.
