Qur'an 15:88 · Al-Hijr

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

(88) 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.
