Messenger of Allah ﷺ said, "If anyone of you looked at a person who was made superior to him in property and (in good) appearance, then he should also look at the one who is inferior to him.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ إِذَا نَظَرَ أَحَدُكُمْ إِلَى مَنْ فُضِّلَ عَلَيْهِ فِي الْمَالِ وَالْخَلْقِ فَلْيَنْظُرْ إِلَى مَنْ هُوَ أَسْفَلَ مِنْهُ
