A true Muslim adheres to the convictions, the religious beliefs; confession of faith or the basic article of Muslim faith and practices. The sources of the Islamic Creed are Qur’an and Sunnah (the life, actions and sayings of Prophet Muhammad, peace be upon him). Islam does not teach an exclusive doctrine, and is not meant exclusively for any single race or people. The Jews claimed their faith for themselves, and the Christianity in the beginning was a sect of the Jews. Even the modern organized Christian churches, though they have been, consciously or unconsciously, influenced by the Time-spirit, including the historical fact of Islam, yet cling to the idea of Vicarious Atonement, which means that all who do not believe; that Jesus died on Cross as a sacrifice to get rid the humanity of Original Sin, or who lived previously to the death of Christ are spiritually at a disadvantage. The approach of Islam is entirely different. Islam existed before the preaching of Muhammad (peace be upon him) on this earth: the Qur’an expressly asks Prophet Muhammad (peace be upon him) to follow the religion of Prophet Abraham, peace be upon him (Qur’an;16:123). It should be kept in view that the Night Journey of Prophet Muhammad (peace be upon him) from Mecca to Jerusalem, immediately preceding his Ascension to heavens (mair’aj), was evidently meant to show that Islam is not a new doctrine but a continuation of the same divine message which was preached by the prophets of old, who had Jerusalem as their spiritual home, This view is supported by Traditions (quoted in Fath al-Bari VII, 158), according to which the Prophet (peace be upon him), during his Night Journey, also offered prayers at Yathrib, Sinai, Bethlehem, etc. His meeting with other prophets, mentioned in this connection, symbolize the same idea. The well-known Traditions to the effect that on the occasion of his Night Journey the Prophet (peace be upon him) led a prayer in the Temple of Jerusalem (Al Aqsa Mosque; The distant place of worship), in which all other prophets ranged themselves behind him, expresses in a figurative manner the doctrine that Islam, as preached by the Prophet Muhammad (peace be upon him), is the fulfillment and perfection of mankind’s religious development. He was the last and the greatest of God’s message-bearers. Islam is the best Din (way of life) because its teachings are not restricted to doctrinaire rhetoric but practical solutions for the problems of mankind at the individual and collective levels. Islam offers the best way of life because it is a practical, universal religion not confined to any ethnic group or nationality but to the humanity, ever since its existence; hence also called the natural faith or the eternal faith. Therefore Islam should be viewed in its broader perspective as true legacy of Prophets [Noah-Abraham-Moses & Jesus] for peace and salvation of humanity. Allah says:
“He hath ordained for you that religion which He commended unto Noah, and that which We inspire in thee (Muhammad), and that which We commended unto Abraham and Mosesand Jesus, saying: Establish the religion, and be not divided therein. Dreadful for the idolaters is that unto which thou callest them. Allah chooseth for Himself whom He will, and guideth unto Himself him who turneth (toward Him). And they were not divided until after the knowledge came unto them, through rivalry among themselves; and had it not been for a Word that had already gone forth from thy Lord for an appointed term, it surely had been judged between them. And those who were made to inherit the Scripture after them are verily in hopeless doubt concerning it. Unto this, then, summon (O Muhammad). And be thou upright as thou art commanded, and follow not their lusts, but say: I believe in whatever Scripture Allah hath sent down, and I am commanded to be just among you.Allah (God) is our Lord and your Lord. Unto us our works and unto you your works; no argument between us and you. Allah will bring us together, and unto Him is the journeying.”(Qur’an;42:13-15)
“Verily this Brotherhood of yours (Muslims) is a single Brotherhood and I am your Lord and Cherisher: therefore serve Me Alone”(Qur’an;21:92).
