﴿ لَلَبِثَ فِى بَطْنِهِۦٓ إِلَىٰ يَوْمِ يُبْعَثُونَ ﴾

“he would indeed have remained in its belly till the Day when all shall be raised from the dead:”

he would have tarried in its belly until the day when they are raised in other words the whale’s belly would have been his tomb until the Day of Resurrection.
