looking down on believers
Allah says: "I don’t say about the people you look down on, ‘Allah will never give them good.’" (Hud: 31)
"We test some people with others, so the rich might say, ‘Are these the ones Allah has blessed?’" (Al-An’am: 53)
Don't judge someone's worth based on how they look or what they have. That’s not your place.
(from Syajaratul Ma‘arif, Syaikh al-‘Izz bin Abdus Salam)
