وَمَاذَا عَلَيۡهِمۡ لَوۡ ءَامَنُواْ بِٱللَّهِ وَٱلۡيَوۡمِ ٱلۡأٓخِرِ وَأَنفَقُواْ مِمَّا رَزَقَهُمُ ٱللَّهُۚ وَكَانَ ٱللَّهُ بِهِمۡ عَلِيمًا ٣٩
And what [harm would come] upon them if they believed in Allāh and the Last Day and spent out of what Allāh provided for them? And Allāh is ever, about them, Knowing.
Translation: Saheeh International (English)
Each word's meaning and sound
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.
