Surah Al-An'aam, Verse 53
وَكَذَٰلِكَ فَتَنَّا بَعْضَهُم بِبَعْضٍۢ لِّيَقُولُوٓا۟ أَهَٰٓؤُلَآءِ مَنَّ ٱللَّهُ عَلَيْهِم مِّنۢ بَيْنِنَآ ۗ أَلَيْسَ ٱللَّهُ بِأَعْلَمَ بِٱلشَّٰكِرِينَ
Translation — Sahih International
And thus We have tried some of them through others that the disbelievers might say, "Is it these whom Allah has favored among us?" Is not Allah most knowing of those who are grateful?
