Ever since the wrath of Heaven destroyed its inhabitants, the country of Thamud is deserted. The abodes of this ungodly people alone were left and are still remaining. Under the brows of their frontals, the wide-open doors look like the pupils of fantastic eyes, dilated by the horror of the formidable sight they witnessed. The crevices scarring the walls seem, likewise, to be mouths distorted by affright and calling out to those who dare set foot in this desolate domain: "Admire by our example, the vanity of mortals' pride and the emptiness of their undertakings. Who can describe the mighty efforts by which our masters carved us out of the heart of the mountain and adorned us with slender pillars and graceful sculpture? Sheltered in our bosom, stronger than iron, were they wrong to reckon that they were in perfect safety?
"How mad were they! In vain their contracted hands clung despairingly to the angles of our walls, the storm of divine wrath passed over them ... and they disappeared for evermore. Even we tottered on our foundations like unto the limbs of a man devoured by fever whose teeth chatter noisily. If we were spared, it was only so that we might serve as a lesson to travellers straying into our mournful land."
When the army of the Believers penetrated into the midst of strangely-shaped stone blocks, emerging like reefs from a sea of sand, and showing in their smooth sides the dark openings that were the abodes of the people of Thamud, the Prophet covered his face with a corner of his mantle, so as to avoid looking at these vestiges of impiety. He closed his mouth and nostrils, not wishing to breathe the impure air emanating from the ruins, and urged on his camel to get away from them as quickly as possible.
Fearing lest irresistible curiosity might lead the Soldiers of Islam astray, he exhorted them thus: 'If ye enter these dens of the ungodly, do so only with tears in your eyes as ye recall their sad fate.' He knew that tears of this kind, welling up by reason of such terrible remembrances, would cause the attraction of curiosity to be dominated by fear of the Almighty. Impressed, however, by the strangeness of these dwellings, seemingly those of superhuman beings or evil spirits; and by the deathly silence that reigned in these parts where formerly a powerful people lived a riotous life of pride and debauchery, the Faithful sought but to follow the example of their inspired guide and flee from the accursed ruins.
Besides, the soldiers were urged onwards by thirst; and when, in the midst of the sandy plains, the famous well of the Thamud people came in sight where the she-camel of the miracle used to drink, they broke their ranks in the greatest disorder, trying to outstrip each other, racing to be the first to slake their thirst. The Prophet, who had been unable to restrain them, hurried along with his she-camel, caught them up, and gave his orders in accents of great severity: 'Beware of that water, tainted by impiety. Take care not to use it for drinking purposes; nor for your ablutions; nor for cooking your food! Let all who have drunk of it, vomit it forth! Those who have kneaded "hays" with it must throw that "hays" to their camels! Those who have used it to cook their victuals must scatter those victuals on the ground without touching them!' To put an end to all temptation, he ordered the march to be resumed, without taking into account the fatigue or the thirst of his troops.
His face still veiled by a fold of his mantle, the Prophet, obeyed and followed blindly by his soldiers, among whom deception and suffering had not caused the slightest murmur, soon reached the entrance to the narrow, weird pass of the "Mabraku'n-Naqa."
Skirted on each side by crags from one hundred and fifty to two hundred cubits high, the dark defile produced the most sinister impression. The Faithful felt their breasts shrinking as if crushed between the dizzy dominating walls. What they most feared was to hear the resounding echoes of the miraculous, disembowelled she-camel. In that case, no power on earth could have mastered the mad terror that must have overwhelmed the animals ridden by the soldiers. By dint of wild leaps and bounds, the camels would have thrown off their loads of arms and food, and ridding themselves of their drivers, taken to flight; when, after throwing down and trampling all those who might have tried to stop them, the men must have been abandoned on foot in the midst of the most frightful of all deserts.
The slightest noises, amplified by the sonorous echoes of the rocky heights, made the Believers start and shudder. They went on in the most profound silence, thinking only of how best to speed their camels. At last the lugubrious passage was traversed; the soldiers' breath came and went normally in their breasts now relieved of all oppression, and a wide, open space, suitable for pitching the tents, offered itself to their gaze.
When the Believers had finished the work of encampment, the Prophet warned them that a heavy tempest would rage during the night, and he enjoined them solemnly: 'Let those in charge of camels tie them securely and no man leave his tent without a companion.'
They had scarcely time to give a look at the hobbles of their beasts than the Prophet's prediction began to come true. The sun had set, covered by a misty veil, contrasting with its habitual sumptuous purple; its rayless pallor was the sign of an extraordinary storm.
