quran:2:156 –

Who, when disaster strikes them, say, "Indeed we belong to Allah, and indeed to Him we will return."  

those who, when they are struck by an affliction, a calamity, say, ‘Surely we belong to God, we are His possession and servants, with whom He does as He pleases; and to Him we will return’, in the Hereafter, whereupon He will requite us: in one hadīth ˹it is said that˺, ‘whoever pronounces the istirjā‘ ˹sc. the formula ‘surely we belong to God and to Him we will return’˺ when an affliction befalls him, God will reward him and compensate him with what is better’. Similarly, it is said that on one occasion when his lamp blew out, the Prophet (s) uttered the istirjā‘, whereupon ‘Ā’isha said to him, saying: ‘But, it is just a lamp’, to which he replied, ‘Whatever bothers a believer is an affliction ˹of sorts˺’: this is reported by Abū Dāwūd in his ˹section on˺ mursal reports.
القرآن:٢:١٥٦ –

الَّذِينَ إِذَا أَصَابَتْهُمْ مُصِيبَةٌ قَالُوا إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ  

هم {الذين إذا أصابتهم مصيبة} بلاء {قالوا إنا لله} ملكا وعبيدا يفعل بنا ما يشاء {وإنا إليه راجعون} في الآخرة فيجازينا وفي الحديث (من استرجع عند المصيبة أجره الله فيها وأخلف الله عليه خيرا) وفيه أن مصباح النبي ﷺ طفئ فاسترجع فقالت عائشة: إنما هذا مصباح فقال: (كل ما أساء المؤمن فهو مصيبة) رواه أبو داود في مراسيله.
