The Messenger of Allah ﷺ as saying: When one of you is afflicted with a calamity, he should say: "We belong to Allah, and to Him we do return." O Allah, I expect reward from Thee from this affliction, so give me reward for it, and give me a better compensation.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَصَابَتْ أَحَدَكُمْ مُصِيبَةٌ فَلْيَقُلْ { إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ } اللَّهُمَّ عِنْدَكَ أَحْتَسِبُ مُصِيبَتِي فَآجِرْنِي فِيهَا وَأَبْدِلْ لِي خَيْرًا مِنْهَا
