Al-Hijr 15:88

La tamuddanna AAaynayka ila mamattaAAna bihi azwajan minhum wala tahzanAAalayhim wakhfid janahaka lilmu/mineen

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.

Never stretch your eyes towards what We have given to groups of them to enjoy, and do not grieve for them, and be kind to believers in humbleness,
