Larry, Thank you for your message and question. I am not used to receiving thanks from readers. I receive insults/comments which I remove
الَّذِينَ إِذَا أَصَابَتْهُم مُّصِيبَةٌ قَالُوا إِنَّا لِلَّهِ وَإِنَّا إِلَيْهِ رَاجِعُونَ
The response that you find is adapted from a verse of Koran typically used in case of death.
The verse 156, verse 2
" Indeed we belong to Allah, and indeed to Him we will return."
It is customary to use it and repeat it in death.
