لَا تَمُدَّنَّ عَيْنَيْكَ إِلَىٰ مَا مَتَّعْنَا بِهِۦٓ أَزْوَٰجًا مِّنْهُمْ وَلَا تَحْزَنْ عَلَيْهِمْ وَٱخْفِضْ جَنَاحَكَ لِلْمُؤْمِنِينَ

La tamuddanna AAaynayka ila mamattaAAna bihi azwajan minhum wala tahzanAAalayhim wakhfid janahaka lilmu/mineen

Do not extend your eyes toward that by which We have given enjoyment to [certain] categories of them [i.e., the disbelievers], and do not grieve over them. And lower your wing [i.e., show kindness] to the believers.
