Truth, (said Abul Coumel) is as the waters of the Zemzem well, a gift which Allah gives to these that believe in him. I delayed to tell thee, my brother, how I became possessed of this talisman, until such time as we should be amongst these rocks, because it was here that I received it, in the manner that I am about to relate. About fifteen years ago, ere the hand of time had mingled my beard with white, I was returning from Cairo to Cossier, after having disposed of all my merchandize to Ibraham Bey, who being a careful and avaricious man, bought up all the goods which came into Egypt, and afterwards retailed them at a great profit to his less provident companions. My heart was glad, because the road to riches was before me, and I forgot the proverb, "In the midst of prosperity there is danger." Accordingly, the slow journeys of the caravan became hateful in my sight, and I lingered on the green banks of the Nile, thinking, with a swift horse, to overtake the rest of my company ere they had proceeded more than a day's journey. I was accompanied by a slave, whose horse carried the bags of water, and early in the morning we set out joyfully on our way; and as we went along the slave sang sweetly, and told many pleasant tales to beguile the time, so that the desert rang to our music and laughter. But it was thus we, forgot to make haste, and when morning broke we had not proceeded half so far as we thought to have done. The hot wind now began to blow; and to gain strength, we took a part of the water we had brought with us, and gave part to our horses, and so we proceeded; but the slave sang no more, and the desert looked the more dreary, because we were alone. We rode on for four hours longer, and then came to the summit of these hills, where we had expected to overtake the caravan; but we looked all around, to the east, and the west, the north, and the south, and not a living thing was within sight; all that we could see was a boundless sky, and a boundless plain, and dry sand, and a burning sun. However, we descended from the hills and took our way along the plain; but silence was upon our lips, for we feared to open our mouths lest we should increase the thirst we had little means to satisfy. At length, after two hours more, the slave said "Master, I thirst," and I bade him take some of the water, but to use it frugally. Nevertheless, he, seeing that I took none, was ashamed to drink before his master, so that we rode on with our thirst still unquenched; and at the end of another hour he said, "Master, I must drink, or I die." So turning round, I beheld that his face was changed, and his eyes had become like blood, and I said, "Drink, why hast thou not slackened thy thirst before?" But he answered not, and in a moment the bridle dropped from his hand, and he fell off his horse upon the sand. It was all in vain that I poured what yet remained of the water into his mouth or upon his forehead.
