حَدَّثَنَا يَحْيَى بْنُ يَحْيَى وَقُتَيْبَةُ بْنُ سَعِيدٍ قَالَ قُتَيْبَةُ حَدَّثَنَا وَقَالَ يَحْيَى أَخْبَرَنَا الْمُغِيرَةُ بْنُ عَبْدِ الرَّحْمَنِ الْحِزَامِىُّ عَنْ أَبِى الزِّنَادِ عَنِ الأَعْرَجِ عَنْ أَبِى هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « إِذَا نَظَرَ أَحَدُكُمْ إِلَى مَنْ فُضِّلَ عَلَيْهِ فِى الْمَالِ وَالْخَلْقِ فَلْيَنْظُرْ إِلَى مَنْ هُوَ أَسْفَلَ مِنْهُ مِمَّنْ فُضِّلَ عَلَيْهِ ».

It was narrated from Abu Hurairah that the Messenger of Allah (s.a.w) said: "If one of you looks at someone who has been given more wealth and physical beauty than he has, let him then look at one who has been given less."
