Still, five times a day, the peculiar cry of the "mullah" is heard from the tower of prayer, giving the signal for the follower of Islam to turn towards Mecca, throw himself on his face, and utter the prescribed words.

Much inspired by this wonderful dream, Mohammed was further encouraged by the news that seventy men of Medina had joined the ranks of Islam and were about to meet him on the hillside beyond Mecca, with intent to induce him, if possible, to take up his future abode in their city, leaving his birthplace to its fate. There, under the dark midnight sky, these men bound themselves to worship Allah only, to obey the Prophet, and to fight in defence of him and his followers.

"And what will be our reward?" asked one.

"Paradise!" replied Mohammed briefly.

And then the oath was sworn; while the Prophet, on his side, promised to live and die with his new converts when the time was ripe.

The meeting had, however, been watched by spies, who reported all to the men of Mecca; and a new persecution arose, so bitter that most of the "Faithful," as the followers of Mohammed came to be called, fled at once to Medina. Mohammed himself remained, hoping that thus he might turn the wrath of the idolaters upon himself and protect the flight of his children.

Presently, however, came information that forty men, one from each tribe, had sworn together to take his life; and forthwith Mohammed with Abu Bekr, his devoted friend, departed one dark night and shook off the dust of Mecca from his feet. Danger was so near that they dared not take the path to Medina, but made their way to a mountain, on whose rocky summit they found a small cave into which they crept at dawn of day.

Knowing what the end of the pursuit would mean, Abu began to lose nerve, and asked, "What if our pursuers should find our cave? We are but two."

"We are three," was the calm reply: "Allah is with us!"

Legend says that the pursuers actually approached the mouth of the cave and were about to investigate it. But in the early hours of the day Allah had caused a tree to grow up before it, a spider to weave its web across it, and a wild pigeon, most timid of birds, to lay eggs in a nest made in the branches; and the searchers, seeing these things, declared it impossible that any one could be within. A faithful friend provided them in secret with food and milk, and on the third night they began the journey to Medina.
