Softening the hearts [Saheeh Bukhaari: Chapter: One should always look at the one who is below him….
Narrated Abu Hurairah (radiyallaahu-anhu): Allaah’s Messenger (sallal-laahu-alayhi-wasallam) said: ”If anyone of you looked at a person who was made superior to him in wealth and (good) appearance, then let him also look at the one who is below him and to whom he has been made superior.” 
Imaam Abdul-Azeez Bin Baaz (rahimahullaah) said: So that he may recognize Allaah’s blessing upon him. And in another narration (it is stated): So that he does not belittle the blessings Allaah has bestowed upon him.
