Believer's responsibility

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَنفِقُوا۟ مِمَّا رَزَقْنَـٰكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا بَيْعٌ فِيهِ وَلَا خُلَّةٌ وَلَا شَفَـٰعَةٌ ۗ وَٱلْكَـٰفِرُونَ هُمُ ٱلظَّـٰلِمُونَ

O you who have believed, spend from that which We have provided for you before there comes a Day in which there is no exchange [i.e., ransom] and no friendship and no intercession. And the disbelievers - they are the wrongdoers.
