Hadith 2
:عن صهيب الرومي قال
قال رسول الله ﷺ: عَجَبًا لأَمْرِ المُؤْمِنِ، إنَّ أمْرَهُ كُلَّهُ خَيْرٌ، وليسَ ذاكَ لأَحَدٍ إلّا لِلْمُؤْمِنِ: إنْ أصابَتْهُ سَرّاءُ شَكَرَ، فَكانَ خَيْرًا له، وإنْ أصابَتْهُ ضَرّاءُ، صَبَرَ فَكانَ خَيْرًا له
صحيح مسلم: ٢٩٩٩
Suhaib al-Rūmī reported that:
The Messenger of Allāh (ﷺ) said, “How wonderful is the situation of a believer; there is good for him in everything and this applies only to a believer. If prosperity befalls him and he expresses gratitude to Allāh, then it will be for his good; and if adversity befalls him and he endures it patiently, it will also be for his good.”
(Ṣaḥīḥ Muslim: 2999)
