Surah Qaf 50:3

أَءِذَا مِتْنَا وَكُنَّا تُرَابًا ۖ ذَٰلِكَ رَجْعٌۢ بَعِيدٌ

When we have died and have become dust, [we will return to life]? That is a distant [i.e., unlikely] return."

Translation: Saheeh International

Tafsir

What! read a-idhā pronouncing both hamzas or not pronouncing the second but inserting an alif between the two in both cases When we are dead and have become dust? shall we return to life? That is a far-fetched return!’ an event that is extremely remote.
