It was at this period of the Prophet's career that a connexion sprang up
between Muhammad and the followers of the Jewish religion. During the Meccan
period it seems quite clear that he looked upon both Christianity and Judaism as
co-ordinate religions, the followers of which would in them find salvation, and
even later on in Madina he could say:
Verily, they who believe (Muslims), and the Jews and the Sabians and the
Christians,whosoever of them believeth in God and in the Last Day And doeth
what is right, on them shall come no fear, neither shall they be put to grief.
Sura Al-Baqarah (ii) 59.
In one of the latest Meccan Suras, he even says that the Jews were very glad
when they heard of his revelations:
They1 to whom we have given the Book rejoice in what hath been
sent down to thee. Sura Ar-Ra'd (xiii) 36.
But although there was during the Meccan period an apparent friendliness with
the Jews, yet Muhammad even then had begun to hint at the subordinate nature of
Judaism, a point in his teaching more fully worked out in Madina. Still, in two
Suras of the middle Meccan period the absolute nature of the claims of Islam are
asserted:
Truly this, your religion, is the one religion. Sura Al-Mu'minun (xxiii) 54.
