When one of you looks at one who stands at a higher level than you in regard to wealth and physical structure he should also see one who stands at a lower level than you in regard to these things (in which he stands) at a higher level (as compared to him). (Using translation from Muslim 2963a)
"إِذَا رأى أحدُكُمْ مَنْ فُضِّل عليه في الخلقِ أو الرِّزْقَ فليَنظُرْ إلى من هُوَ أسْفلَ منه مِمن فُضِّلَ هو عليه".
