Al-Hijr 15:88

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

Lā tamuddanna ʿaynayka ilā mā mattaʿnā bihi azwājan min'hum walā taḥzan ʿalayhim wa-ikh'fiḍ janāḥaka lil'mu'minīna

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.
