Quran Ibrahim 14:31

قُل لِّعِبَادِيَ ٱلَّذِينَ ءَامَنُواْ يُقِيمُواْ ٱلصَّلَوٰةَ وَيُنفِقُواْ مِمَّا رَزَقۡنَٰهُمۡ سِرّٗا وَعَلَانِيَةٗ مِّن قَبۡلِ أَن يَأۡتِيَ يَوۡمٞ لَّا بَيۡعٞ فِيهِ وَلَا خِلَٰلٌ

Translation

[O Muḥammad], tell My servants who have believed to establish prayer and spend from what We have provided them, secretly and publicly, before a Day comes in which there will be no exchange [i.e., ransom], nor any friendships.
