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.
حَدَّثَنَا هَدَّابُ بْنُ خَالِدٍ الأَزْدِيُّ، وَشَيْبَانُ بْنُ فَرُّوخَ، جَمِيعًا عَنْ سُلَيْمَانَ بْنِ الْمُغِيرَةِ، - وَاللَّفْظُ لِشَيْبَانَ - حَدَّثَنَا سُلَيْمَانُ، حَدَّثَنَا ثَابِتٌ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي لَيْلَى، عَنْ صُهَيْبٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏
"‏ عَجَبًا لأَمْرِ الْمُؤْمِنِ إِنَّ أَمْرَهُ كُلَّهُ خَيْرٌ وَلَيْسَ ذَاكَ لأَحَدٍ إِلاَّ لِلْمُؤْمِنِ إِنْ أَصَابَتْهُ سَرَّاءُ شَكَرَ فَكَانَ خَيْرًا لَهُ وَإِنْ أَصَابَتْهُ ضَرَّاءُ صَبَرَ فَكَانَ خَيْرًا لَهُ ‏"‏ ‏.‏
