بَلَىٰ مَنْ أَسْلَمَ وَجْهَهُۥ لِلَّهِ وَهُوَ مُحْسِنٌۭ فَلَهُۥٓ أَجْرُهُۥ عِندَ رَبِّهِۦ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ
Nay, but whosoever surrendereth his purpose to Allah while doing good, his reward is with his Lord; and there shall no fear come upon them neither shall they grieve.
