Verse 31

قُل لِّعِبَادِىَ ٱلَّذِينَ ءَامَنُوا۟ يُقِيمُوا۟ ٱلصَّلَوٰةَ وَيُنفِقُوا۟ مِمَّا رَزَقْنَـٰهُمْ سِرًّا وَعَلَانِيَةً مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌ لَّا بَيْعٌ فِيهِ وَلَا خِلَـٰلٌ

Tell my faithful servants to uphold the contact prayer and spend from what We have provided for them secretly and publicly, before a day comes wherein there is neither trade nor nepotism.
