وَتَحْسَبُهُمْ أَيْقَاظًۭا وَهُمْ رُقُودٌۭ ۚ وَنُقَلِّبُهُمْ ذَاتَ ٱلْيَمِينِ وَذَاتَ ٱلشِّمَالِ ۖ وَكَلْبُهُم بَٰسِطٌۭ ذِرَاعَيْهِ بِٱلْوَصِيدِ ۚ لَوِ ٱطَّلَعْتَ عَلَيْهِمْ لَوَلَّيْتَ مِنْهُمْ فِرَارًۭا وَلَمُلِئْتَ مِنْهُمْ رُعْبًۭا
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.
Surah Al-Kahf(18:18)
