﴿ إِنَّ ٱلَّذِينَ يَتْلُونَ كِتَٰبَ ٱللَّهِ وَأَقَامُوا۟ ٱلصَّلَوٰةَ وَأَنفَقُوا۟ مِمَّا رَزَقْنَٰهُمْ سِرًّۭا وَعَلَانِيَةًۭ يَرْجُونَ تِجَٰرَةًۭ لَّن تَبُورَ ﴾

“(It is) they who [truly] follow God’s revelation, and are constant in prayer, and spend on others, secretly and openly, out of what We provide for them as sustenance - it is they who may look forward to a bargain that can never fail,”
