The prince, now more assured than ever that he was the favourite of Allah and the prophet, after offering up prayers with a relieved heart, slept comfortably in a building creeled on the margin of the reservoir, and was only awakened by the call of the sultan at sun-rise, who was more astonished at the accomplishment of this labour than the former, though certainly each was equally difficult.  He conducted the prince to his palace, and the day was spent in the highest festivity.

At the approach of night the prince was conducted to his third task, which was to complete and fit up before daylight from a vast mass of planks of the choicest timber ready stored the doors, windows, and balconies of an unfinished palace, much larger than that which the sultan inhabited.  The prince at the apprehension of the consequences of failure was somewhat alarmed; but the recollection of his former aids supported him, and after offering up his devotions he sat down, composedly waiting for the decision of Providence on his fate.  His resignation was accepted, for at midnight he was roused from his contemplations by the sounds of sawing, planing, hammering, nailing, and the songs of happy work-men.  Looking up he perceived his friends of the iron mountains; who, all saluting him, cried out, “Prince, set your heart at rest, for we are come to repay you for your hospitable feast.”  Before daylight the palace was fitted up in a manner more elegant than can be described, and every door, window, and balcony painted with the most brilliant colours, flowered with silver and gold.  The grateful labourers of the iron mountains having finished their work, respectfully saluted the prince and departed.

The prince having taken a grateful leave of his useful friends, walked through the palace, and was eagerly employed in admiring its elegance and the magnificence of their finishing hand, when the sultan Amir bin Naomaun, who from his apartments at sun-rise had observed the miraculous completion, appeared, having hastened to examine the superb workmanship, and to congratulate his son-in-law, for as such he now acknowledged him, and as the favoured of Allah, and of the last of prophets.  He conducted the prince to the palace, and the most magnificent preparations being made, the nuptials with his daughter were celebrated in the new edifice, where the bride and bridegroom enjoyed themselves for three months, at the expiration of which the prince begged permission to return to his father’s dominions, which he reached just in time to release him from the attack of an inimical sultan, who had invaded the country, and laid close siege to his capital.  His father received him with rapture, and the prince having made an apology to the sultana for his former rude behaviour, she received his excuses, and having no child of her own readily adopted him as her son; so that the royal family lived henceforth in the utmost harmony, till the death of the sultan and sultana, when the prince succeeded to the empire.
