Do not extend your eyes toward that by which We have given enjoyment to [certain] categories of the disbelievers, and do not grieve over them. And lower your wing to the believers
The Saheeh International Quran Translation
لَا تَمُدَّنَّ عَيْنَيْكَ إِلَىٰ مَا مَتَّعْنَا بِهِۦٓ أَزْوَٰجًا مِّنْهُمْ وَلَا تَحْزَنْ عَلَيْهِمْ وَٱخْفِضْ جَنَاحَكَ لِلْمُؤْمِنِينَDo not extend your eyes toward that by which We have given enjoyment to [certain] categories of the disbelievers, and do not grieve over them. And lower your wing to the believers
