Sura 18 Aya 18

Translator	Translation
Ali Quli Qara'i	You will suppose them to be awake, although they are asleep. We turn them to the right and to the left, and their dog [lies] stretching its forelegs at the threshold. If you come upon them, you will surely turn to flee from them, and you will surely be filled with a terror of them.
Pickthal	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.
Shakir	And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them.
Yusufali	Thou wouldst have deemed them awake, whilst they were asleep, and We turned them on their right and on their left sides: their dog stretching forth his two fore-legs on the threshold: if thou hadst come up on to them, thou wouldst have certainly turned back from them in flight, and wouldst certainly have been filled with terror of them.
