﴿ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُم بِٱلَّيْلِ وَٱلنَّهَارِ سِرًّۭا وَعَلَانِيَةًۭ فَلَهُمْ أَجْرُهُمْ عِندَ رَبِّهِمْ وَلَا خَوْفٌ عَلَيْهِمْ وَلَا هُمْ يَحْزَنُونَ ﴾

“Those who spend their possessions [for the sake of God] by night and by day, secretly and openly, shall have their reward with their Sustainer; and no fear need they have, and neither shall they grieve.”

(Those who spend their wealth) in charity (by night and day, in secret and openly, surely their reward is with their Lord) in Paradise, (and there shall no fear come upon them) perpetually (neither shall they grieve) when others do. This verse was revealed about 'Ali Ibn Abi Talib.
