(13) باب الْمُؤْمِنُ أَمْرُهُ كُلُّهُ خَيْرٌ
Suhaib reported that Allah's Messenger (ﷺ) said:
Strange are the ways of a believer for there is good in every affair of his and this is not the case with anyone else except in the case of a believer for if he has an occasion to feel delight, he thanks (God), thus there is a good for him in it, and if he gets into trouble and shows resignation (and endures it patiently), there is a good for him in it.
