When the time of pilgrimage again arrived, Muḥammad found himself surrounded by an enthusiastic band of seventy disciples from al-Madīnah, who in a secret defile at Minā plighted their faith, the second Pledge of ʿAqabah, whereby they promised to receive and defend the Faith at the risk of their own lives. After this Muḥammad determined to quit Makkah, and the command was given, “Depart unto al-Madīnah, for the Lord hath verily given you brethren in that city, and a house in which ye may find refuge.” And so, abandoning house and home, the Muslims set out secretly in little parties for al-Madīnah, where the numbers soon reached to about one hundred and fifty, counting women and children. Muḥammad, with Abū Bakr and ʿAlī, with their families, were left almost alone in Makkah. The Quraish held a council, and determined to slay Muḥammad; but being warned of their designs, he escaped to Mount S̤aur, near Makkah, where he hid himself three days in a cave, and after three more days he reached al-Madīnah.

The day of his flight, or hijrah, marks the Muḥammadan era, or Hegira. The date of the flight was the 4th of Rabīʿu ʾl-Awwal, and by the calculations of M. Caussin de Perceval, the 20th of June, A.D. 622. [[HIJRAH].]

The flight to al-Madīnah changes the scene, and with it the character of the portions of the Qurʾān revealed there. He who at Makkah is the admonisher and persuader, at al-Madīnah is the legislator and the warrior, and the verses of the Qurʾān assume a more didactic tone. Poetry makes way for prose, and he openly assumes the office of a public warner and prophet.

The idolaters of Makkah disappear and their place is taken by the hypocrites [[MUNAFIQUN]] of al-Madīnah. Here at al-Madīnah there was no opposition to Muḥammad and his doctrines; but, nevertheless, an undercurrent of disaffection prevailed. The head of the party was ʿAbdu ʾllāh ibn Ubaiy, who, but for the new turn in the fortunes of the city was on the point of being its chief. These disaffected citizens, the munāfiqūn, or “hypocrites,” as they are called, continued to be the objects of bitter denunciation in the Qurʾān till near the close of the Prophet’s career. But before the success of Islām they too vanish from the scene.

The first year of Muḥammad’s residence at al-Madīnah was chiefly occupied in building the great mosque [[MASJIDU ʾN-NABI]], and in providing houses for himself and his followers. In a short time he became the recognised chief of the city. The mosque and the houses were finished within seven months of Muḥammad’s arrival. About the middle of the winter he left the house of Abū Aiyūb, with whom he had been staying, and installed Saudah in her new residence. Shortly afterwards he celebrated his nuptials with ʿĀyishah, who, though she had been three years affianced, was but a girl of ten years.

Thus, at the age of fifty-three, a new phase commenced in the life of Muḥammad. Hitherto limiting himself to a single wife, he had shunned the indulgence, but he now surrounds himself with the cares and discord of polygamy. The unity of his family was now broken, never again to be restored. Thenceforward his love was to be claimed, his attentions shared by a plurality of wives, and his days spent between their houses, for Muḥammad had no separate apartments of his own.

Those Muslims who had left Makkah with the Prophet and settled in al-Madīnah, were now known as the Refugees [[MUHAJIRUN]] whilst those who embraced the faith at al-Madīnah, were designated the Assistants or Allies [[ANSAR]]. Both these names in time became titles of distinguished honour.

In the second year of the Ḥijrah, Muḥammad commenced hostilities against the Quraish, and the first pitched battle took place at Badr. With an army of 305 followers, of whom two-thirds were citizens of al-Madīnah, Muḥammad routed a force three times the number. The following graphic description of the battle of Badr is given by Sir William Muir. (New ed. p. 230.)

“The valley of Badr consists of a plain, with steep hills to the north and east; on the south is a low rocky range; and on the west rise a succession of sandy hillocks. A rivulet, rising in the inland mountains, runs through the valley, producing along its course numerous springs, which here and there were dug into cisterns for the accommodation of travellers. At the nearest of these springs, the army of Mahomet halted. Habâl, a citizen of Medîna, advised him to proceed onwards. ‘Let us go,’ he said, ‘to the farthest spring, on the side of the enemy. I know a never-failing fountain of sweet water there; let us make that our reservoir, and destroy the other wells.’ The advice was good. It was at once adopted, and the command of the water thus secured.

“The night was drawing on. So they hastily constructed near the well a hut of palm branches, in which Mahomet and Abu Bakr slept. Sâd ibn Muâdz (Saʿd ibn Muʿāẕ) kept watch by the entrance with his drawn sword. It rained during the night, but more heavily towards the camp of the Coreish. The Moslim army, wearied with its long march, enjoyed sound and refreshing sleep. The dreams of Mahomet turned upon his enemies, and they were pictured to his imagination as a weak and contemptible force.
