Sura Ibrāhīm 14:31

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

qul li-ʿibādiya lladhīna āmanū yuqīmū l-ṣalāta wa-yunfiqū mimmā razaqnāhum sirran wa-ʿalāniyatan min qabli an yaʾtiya yawmun lā bayʿun fīhi wa-lā khilālun

Speak to my servants who have believed, that they may establish regular prayers, and spend (in charity) out of the sustenance we have given them, secretly and openly, before the coming of a Day in which there will be neither mutual bargaining nor befriending.
