The unity of God is in itself a powerful factor in promoting beneficent relations between mankind, of emphasis on the unity of man tends in the same direction. But Islam does not stop there. It goes much further. It teaches that the Divine attribute of Providence has manifested itself not only in making provision for the material needs of man, but has, through the ages, made provision for his spiritual guidance also. Consequently, Islam requires belief not only in the truth and righteousness of the Holy Prophet^(sa) of Islam and in the truth of the revelation vouchsafed to him, but also in the truth and righteousness of all prophets, and in the truth of all Divine revelations. This is repeatedly affirmed in the Qur’an. For instance:

Say, `We believe in Allah and in that which has been revealed to as, and that which was revealed to Abraham and Ishmael and Isaac and Jacob and the Tribes, and that which was given to Moses and Jesus and other Prophets from their Lord. We make no distinction between any of them, and to Him we submit.’ (Ch.3: V.85)

As regard previous revelations, the attitude of Islam may be judged from among others the following:

Surely, We sent down the Torah wherein was guidance and light. By it did the Prophets, who were obedient to Us Judge for the Jews, as did the godly people and those learned in the Law;… (Ch.5: V.45)

And again :

And We caused Jesus, son of Mary, to follow in their footsteps, fulfilling that which was revealed before him in the Torah; and We gave him the Gospel which contained guidance and light fulfilling that which was revealed before it in the Torah and a guidance and an admonition for the God fearing. (Ch.5: V.47)
