We often utter or hear these words when we hear passing of a person or when we are faced with a calamity.
In reality we must keep unfailingly the proclamation of “we only belong to Allah, the Al-mighty Who Created us” in our remembrance at all times, certainly this is our aqeedah.
Although this verse is made sunnah to proclaim when we are affected with a musibah or when we hear the death of a believer but this verse and its message must be always within our consciousness as long as we are living in this world and preparing our life to go back to Allah swt one day.
Allah swt says :
ٱلَّذِينَ إِذَآ أَصَـٰبَتْهُم مُّصِيبَةٌۭ قَالُوٓا۟ إِنَّا لِلَّهِ وَإِنَّآ إِلَيْهِ رَٰجِعُونَ
“Who say, when afflicted with calamity: “To Allah We belong, and to Him is our return”
(2:156 )
Ya Allah, we beg You to forgive us for our heedless, and for the state of forgetfulness to proclaim that we only belong to You. Ameen ameen ameen Ya Allah.
