يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَنفِقُوا۟ مِمَّا رَزَقْنَٰكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌۭ لَّا بَيْعٌۭ فِيهِ وَلَا خُلَّةٌۭ وَلَا شَفَٰعَةٌۭ ۗ وَٱلْكَٰفِرُونَ هُمُ ٱلظَّٰلِمُونَ
O ye who believe! spend of that wherewith We have provided you ere a day come when there will be no trafficking, nor friendship, nor intercession. The disbelievers, they are the wrong-doers.
