Al-Hijr - 15:88

لاَ تَمُدَّنَّ عَيْنَيْكَ إِلَى مَا مَتَّعْنَا بِهِ أَزْوَاجًا مِّنْهُمْ وَلاَ تَحْزَنْ عَلَيْهِمْ وَاخْفِضْ جَنَاحَكَ لِلْمُؤْمِنِينَ
[15:88]
Do not strain your eyes after what We have given certain classes of them to enjoy, and do not grieve for them, and make yourself gentle to the believers.
Strain not thine eyes. (Wistfully) at what We have bestowed on certain classes of them, nor grieve over them: but lower thy wing (in gentleness) to the believers.
Strain not thine eyes toward that which We cause some wedded pairs among them to enjoin, and be not grieved on their account, and lower thy wing (in tenderness) for the believers.
