The leaders of Quraysh were pleased to hear all this and
seizing on what seemed to them a very good opportunity,
agreed to the plan and began to gather together a formidable
army. In the meantime in Medinah, only one Jewish tribe, the
Bani Quraydhah, refused to betray the Muslims.

Eventually the Muslims learned of the preparations being
made for war in Mecca and of the plotting of the Jews within
Medinahitself. The betrayal of the Muslims by the Jews did not
surprise the Prophet (Pbuh), who said of them: 'The hearts of
the Jews have become closed to the truth. They have
forgotten what Muses taught them long ago that there is only
one God.'
In the Name of Allah, the Beneficent, the Merciful
“The likeness of those who are entrusted with the Law of
Moses, yet apply it not, is as the likeness of the ass carrying
books. Evil is the likeness of the people who deny the
revelations of Allah. And Allah guideth not wrongdoing folk”.
(Koran lxii.5)
The Muslims wondered how they could defend Medinah.
They heard that Abu Sufyan was coming to attack them with
an enormous army which included many other Arab tribes, as
well as Quraysh. What were they to do with only a single week
to prepare? The Prophet (Pbuh) and his men knew that it
would be impossible for them to fight off all these tribes! The
only thing they could do was to stay inside the city and try to
defend it as best they could. Now among the people of
Medinah was a Persian named Salman, who had to live in the
city some time before the Prophet's arrival there. As a convert
to Christianity he had traveled to Medinah after Christian
sages had told him that a Prophet would be born in Arabia. On
arriving in he was, however, sold into slavery by the
merchants with whom he had traveled. Later he became a
Muslim, gained his freedom and became a member of the
Prophet's household.
