تَرَى ٱلظَّٰلِمِينَ مُشْفِقِينَ مِمَّا كَسَبُوا۟ وَهُوَ وَاقِعٌۢ بِهِمْ ۗ وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ فِى رَوْضَاتِ ٱلْجَنَّاتِ ۖ لَهُم مَّا يَشَآءُونَ عِندَ رَبِّهِمْ ۚ ذَٰلِكَ هُوَ ٱلْفَضْلُ ٱلْكَبِيرُ
Thou seest the wrong-doers fearful of that which they have earned, and it will surely befall them, while those who believe and do good works (will be) in flowering meadows of the Gardens, having what they wish from their Lord. This is the great preferment.
