“Amazing is the affair of the believer. His affair for him is all good, and this is for none except the believer. If he is touched by something good and he gives thanks, then it is good for him. And if he is touched by a calamity or hardship and he is patient then this is good for him.”
– The Prophet Muhammad, sallallahu alayhi wa sallam. Reported in Saheeh Muslim, The Book of Abstinence and Heart-Melting Narrations (كتاب الزهد والرقائق), Hadeeth (#2999).
