فَلَمْ يَكُ يَنفَعُهُمْ إِيمَانُهُمْ لَمَّا رَأَوْا بَأْسَنَا سُنَّتَ اللَّهِ الَّتِي قَدْ خَلَتْ فِي عِبَادِهِ وَخَسِرَ هُنَالِكَ الْكَافِرُونَ
[40:85]
But their belief was not going to profit them when they had seen Our punishment; (this is) Allah's law, which has indeed obtained in the matter of His servants, and there the unbelievers are lost.
But their professing the Faith when they (actually) saw Our Punishment was not going to profit them. (Such has been) Allah's Way of dealing with His Servants (from the most ancient times). And even thus did the Rejecters of Allah perish (utterly)!
But their faith could not avail them when they saw Our doom. This is Allah's law which hath ever taken course for His bondmen. And then the disbelievers will be ruined.
