Surah Al-Hijr 15:88

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

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.

Translation: Saheeh International

Tafsir

Do not extend your glance toward that which We have given different groups of them to enjoy and do not grieve for them should they not believe and lower your wing temper your nature for the believers.
