Key Verses

1. 18:18Al-Kahf
   وَتَحۡسَبُهُمۡ أَيۡقَاظٗا وَهُمۡ رُقُودٞۚ وَنُقَلِّبُهُمۡ ذَاتَ ٱلۡيَمِينِ وَذَاتَ ٱلشِّمَالِۖ وَكَلۡبُهُم بَٰسِطٞ ذِرَاعَيۡهِ بِٱلۡوَصِيدِۚ لَوِ ٱطَّلَعۡتَ عَلَيۡهِمۡ لَوَلَّيۡتَ مِنۡهُمۡ فِرَارٗا وَلَمُلِئۡتَ مِنۡهُمۡ رُعۡبٗا
   And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.
   In context

   You - O one who looks at them - will think they are awake, because their eyes are open, though in actual fact they are asleep. I turn them over in their sleep, sometimes to the right and sometimes to the left, so that the earth does not consume their bodies. Their dog that accompanied them stretches out its forelegs at the entrance of the cave.
