Al-Baqarah 2:156
ٱلَّذِينَ إِذَآ أَصَـٰبَتْهُم مُّصِيبَةٌ قَالُوٓا۟ إِنَّا لِلَّهِ وَإِنَّآ إِلَيْهِ رَٰجِعُونَ
Allatheena itha asabat-hummuseebatun qaloo inna lillahi wa-innailayhi rajiAAoon
"Who, when disaster strikes them, say, "Indeed we belong to Allāh, and indeed to Him we will return.""
Al-Baqarah 2:156, translation by Sahih International
A short reflection
Indeed we belong to Allah and to Him we shall return. The sentence to keep on the tongue.
