وَيَٰقَوْمِ لَآ أَسْـَٔلُكُمْ عَلَيْهِ مَالًا ۖ إِنْ أَجْرِىَ إِلَّا عَلَى ٱللَّهِ ۚ وَمَآ أَنَا۠ بِطَارِدِ ٱلَّذِينَ ءَامَنُوٓا۟ ۚ إِنَّهُم مُّلَٰقُوا۟ رَبِّهِمْ وَلَٰكِنِّىٓ أَرَىٰكُمْ قَوْمًۭا تَجْهَلُونَ
And O my people! I ask of you no wealth therefor. My reward is the concern only of Allah, and I am not going to thrust away those who believe - Lo! they have to meet their Lord! - but I see you a folk that are ignorant.
