“A man is sometimes saddened by something that passed him by, not realizing that he could never had attained it, even if he tried. And a man sometimes rejoices with something he attains, not realizing it would never have missed him, even if he never sought it out.
Only those things that bring you an increase in the hereafter should please you and you should only be saddened with things that lessen your rank in the next life.”
-Ali (R.A)
