﴿ 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,”

(Lo! those who read the Scripture of Allah) those who read the Qur'an, i.e. Abu Bakr and his fellow believers, (and establish worship) and perform the five daily prayers, (and spend) in charity (of that which We have bestowed on them) of wealth (secretly) between them and Allah (and openly) in front of people, (they look forward to imperishable gain) i.e. Paradise,
