The city of at̤-T̤āʾif, trusting to its natural strength, constituted itself a centre of disaffection; but at last, driven to extremities, and seeing that all the neighbouring tribes had one by one submitted, its chief, after a vain attempt to obtain some relaxation in the rules of Islām, consented to the destruction of the adored idol al-Lāt, and adopted the new faith.

It was during the time of the next yearly pilgrimage (March, A.D. 631), that Muḥammad issued an important command, the crowning stone of the system he had raised, which shows at once the power he wielded, and the strong hold his doctrines had already taken throughout Arabia. Refusing to be present himself during the ceremonies of the pilgrimage, he commissioned ʿAlī to announce to the assembled multitudes in the valley of Minā, that, at the expiration of the four sacred months, the Prophet would hold himself absolved from every obligation or league with idolaters; that after that year no unbeliever would be allowed to perform the pilgrimage, or to visit the holy places; and further, he gave directions that either within or without the sacred territory, war was to be waged with them, that they were to be killed, besieged, and laid in wait for “wheresoever found.” He ordains, however, that if they repent and pay the legal alms, they are to be dismissed freely; but as regards “those unto whom the Scriptures have been delivered” (Jews and Christians, &c.), “they are to be fought against until they pay tribute by right of subjection, and are reduced low.”

“Such, then,” says Sir William Muir, “is the declared mission of Islam, arrived at by slow, though inevitable steps, and now imprinted unchangeably upon its banners. The Jews and Christians, and perhaps the Magians,—‘people of the book’—are to be tolerated, but held in subjection, and under tribute; but for the rest, the sword is not to be sheathed till they are exterminated, or submit to the faith which is to become ‘superior to every other religion.’ ”

About the middle of the year, a heavy grief fell upon Muḥammad, in the death of his little son Ibrāhīm.

On the return of the sacred month (March, A.D. 632), Muḥammad, accompanied by all his wives, selected his victims, assumed the pilgrim garb, and set out on what is called Ḥajjatu ʾl-Wadāʿ, or “The Valedictory Pilgrimage,” to the holy places, from which every trace of the old superstition had been removed, and which, in accordance with his orders of the previous year, no idolater was to visit. Approaching the Kaʿbah by the gate of the Banū Shaibah, he carefully performed all the ceremonies of the ʿUmrah, or “lesser Pilgrimage,” and then proceeded to consummate those of the greater. On the 8th of the holy month Ẕū ʾl-Ḥijjah, he rode to the Wādī Minā, some three miles east of Makkah, and rested there for the night. Next day, passing Muzdalifah, the midway station, he reached in the evening the valley in which stands the granite hill of ʿArafah. From the “summit he spoke to the pilgrims regarding its sacred precincts, announced to them the perfecting of their religion,” offered up the prescribed prayers, and hurried back to Muzdalifah for the night. On the 10th, proceeding to Minā, he cast the accustomed stones, slew the victims brought for sacrifice, had his head shaved and his nails pared, ordering the hair, &c., to be burnt; and, the ceremonies ended, laid aside the pilgrim garb. At Minā, during his three days’ stay, he preached to the pilgrims, called them to witness that he had faithfully fulfilled his mission, and urged them not to depart from the exact observances of the religion which he had appointed. Returning to Makkah, he again went through the ceremonies of the ʿUmrah, made the circuit of the temple, drank of the well Zamzam, prayed in the Kaʿbah, and thus, having rigorously performed all the ceremonies, that his example might serve as a model for all succeeding time, he turned to al-Madīnah.

The excitement and fatigue of his journey to the holy places told sensibly on his health, which for some time had shown indications of increasing infirmity. In the death of Ibrāhīm he had received a blow which weighed down his spirit; the poison of K͟haibar still rankled in his veins, afflicted him at times with excruciating pain, and bowed him to the grave. His life had been a hard and a stirring one, and now the important affairs of his spiritual and temporal kingdom, and the cares of his large domestic circle, denied him that quiet and seclusion for which he longed.

The news of the Prophet’s failing health was soon noised abroad, and tended to encourage his rivals to increased energy of action. Three different revolts, each headed by a dangerous competitor, were now on the point of breaking out. The first of these was led by Musailimah, a rival prophet, who now stated that Muḥammad had distinctly nominated him as his successor [[MUSAILIMAH]]; the second, by Aswad, a wealthy and eloquent rival, with a considerable following [[ASWAD]]; and the third, by T̤ulaiḥah, a famous warrior of Najd, who claimed the prophetic office.

In the Traditions it is related that Musailimah addressed a letter to Muḥammad, which ran:—

“Musailimah, the Prophet of God, to Muḥammad, the Prophet of God. Peace be to you. I am your associate. Let the exercise of authority be divided between us. Half the earth is mine, and half belongs to the Quraish. But the Quraish are a greedy people, and will not be satisfied with a fair division.”

To this presumptuous epistle Muḥammad replied:—
