The Difference Between Show-Off & Self-Admiration, By Ibn Taymiyyah
Ibn Taymiyyah said when differentiating between self-admiration and show-off:
“Self-admiration is akin to showing off, but showing off is a kind of including people as a motive for one’s efforts, whereas self-admiration is including oneself with Allaah (swt) (in the sense that one remembers one’s talent but forgets that they all come from Allaah and by His help).
So the show-off is not fulfilling the words, “You (alone) we worship“, [1:5] and the one who admires himself is not fulfilling the words, “and You (alone) we ask for help,” [1:5] because the one who fulfils the words “You (lone) we worship” will avoid showing off, and the one who fulfils the words “and You (alone) we ask for help” will avoid self-admiration.”
