انْظُرُوا إِلَى مَنْ هُوَ أَسْفَلَ مِنْكُمْ وَلاَ تَنْظُرُوا إِلَى مَنْ هُوَ فَوْقَكُمْ فَهُوَ أَجْدَرُ أَنْ لاَ تَزْدَرُوا نِعْمَةَ اللَّهِ عَلَيْكُمْ

The Messenger of Allah (ﷺ) said: 'Look at the one who is below you and do not look at the one who is above you, for that is more likely to prevent you from belittling the blessings of Allah.'
