قُل لِعِبادِيَ الَّذينَ آمَنوا يُقيمُوا الصَّلاةَ وَيُنفِقوا مِمّا رَزَقناهُم سِرًّا وَعَلانِيَةً مِن قَبلِ أَن يَأتِيَ يَومٌ لا بَيعٌ فيهِ وَلا خِلالٌ

Tell My servants who have believed to establish their prayers and to give from what We provide for them, secretly and openly, before the arrival of a day in which there will be neither bargaining nor befriending.
