وَمِنْهُم مَّن يَقُولُ ٱئْذَن لِّى وَلَا تَفْتِنِّىٓ ۚ أَلَا فِى ٱلْفِتْنَةِ سَقَطُوا۟ ۗ وَإِنَّ جَهَنَّمَ لَمُحِيطَةٌۢ بِٱلْكَٰفِرِينَ
Of them is he who saith: Grant me leave (to stay at home) and tempt me not. Surely it is into temptation that they (thus) have fallen. Lo! hell verily is all around the disbelievers.
