Sadness departs with a prostration (sajdah)

“Sadness departs with a prostration (sajdah). Happiness comes with a sincere supplication (du’ā). Allāh does not forget the good you do, nor does He forget the good you did to others and the pain you relieved them from. Nor will He forget the eye which was about to cry but you made it laugh. Live your life with this principle: be good even if you do not receive good; not because of other’s sake but because Allāh loves the good-doers.”

~ Ibn Al Qayyim
