Dear Brother,
Indeed, since those Books are revealed scriptures and those who brought them were prophets, it is necessary and certain that they should have mentioned the one who would supersede their religions, change the shape of the universe, and illuminate half the earth with the light he brought. Is it possible that those scriptures, which foretold insignificant events, would not speak of the most important phenomenon of humanity, the prophethood of Muhammad (PBUH)? Yes, since they would certainly speak of it, they would either denounce it as a falsehood and so save their religions from destruction and their books from abrogation, or they would affirm it, and through that man of truth, save their religions from superstition and corruption. Now, both friend and foe agree that there is no sign of any such denouncement in the scriptures, in which case there must be affirmation.
God’s Noble Messenger (Upon whom be blessings and peace) says to them through the tongue of the Qur’an: “Your scriptures describe and confirm me; they confirm me in the things I say.” He challenges them with verses such as,
Say, “Bring the Torah and read it, if you are men of truth!”
Say, “Come, let us gather together, our sons and your sons, our women and your women, ourselves and yourselves; then let us earnestly pray and invoke the curse of God on those who lie!” Qur’an, 3:61.
Despite his continuously taunting them with verses such as these, no Jewish scholar or Christian priest was able to show he had made any error. If they had been able to, those very numerous and very obdurate and jealous unbelievers and dissembling Jews and the whole world of unbelief would have proclaimed it everywhere. The Prophet also said:
“Either you find any error of mine, or I shall fight you until I destroy you!” And they chose war and wretchedness. That means they could not find any error. For if they had, they would have been saved from all that.
The words of the Torah, the Bible, and the Psalms do not have the miraculousness of those of the Qur’an. They have also been translated again and again, and a great many alien words have become intermingled with them. Also, the words of commentators and their false interpretations have been confused with their verses. In addition, the distortions of the ignorant and the hostile have been incorporated into them. In these ways, the corruptions and alterations have multiplied in those Books. In fact, Shaykh Rahmat Allah al-Hindi, the well-known scholar, proved to Jewish and Christian scholars and priests thousands of corruptions in them, and silenced them. Nevertheless, despite these corruptions, in our times the celebrated Husayn Jisri (May God have mercy on him) extracted one hundred and ten indications to the prophethood of Muhammad (PBUH), and included them in his Risalat al-Hamidiya.
