And what [harm would come] upon them if they believed in Allah (4:39)

﴿وَمَاذَا عَلَيْهِمْ لَوْ آمَنُوا بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَأَنفَقُوا مِمَّا رَزَقَهُمُ اللَّهُ ۚ وَكَانَ اللَّهُ بِهِمْ عَلِيمًا﴾
[ النساء: 39]

4:39 And what [harm would come] upon them if they believed in Allah and the Last Day and spent out of what Allah provided for them? And Allah is ever, about them, Knowing.

What harm would it have done these people if they had faith in Allah and the Last Day and had spent their wealth for Allah’s sake, being sincere to Him? Rather, they would have received everything that is good by doing so.
Allah has full knowledge of them.
Nothing about them is hidden from Him and everyone will be rewarded according to what they do.

And what loss have they if they had believed in Allah and in the Last Day, and they spend out of what Allah has given them for sustenance? And Allah is Ever All-Knower of them.
