everywhere, and prompted even his friends to treachery. The Beni Aamir,
a branch of the great Hawazin tribe dwelling between the Beni Asad and
the Beni Lahyan, were friendly towards Medina, and sent Mahomet gifts as
a guarantee. These Mahomet refused to receive unless the tribe became
converts to Islam. He knew the danger of compromise--his Meccan
experiences had not faded from his mind; moreover, he recognised that in
his present weakened position firmness was essential. He could not open

But their chief would not be so coerced, neither would he give up his

another branch of the same tribe. This leader, Aamir ibn Sofail,
immediately put the messenger to death, and called upon his allies to
exterminate the followers of the blasphemous Prophet. But the tribe
refused to break Abu Bera's pledge, so Aamir, determined to root them

proudly confident in their ability to elude pursuit. The news was carried
to Mahomet, and at first he was convinced that Abu Bera had betrayed him.
His followers, who had brought the news, had fallen upon and killed some
