The human race began from one man: Adam. Adam, the first man on earth, was also appointed as the first Prophet of God. He revealed His religion-Islam to him Adam, the first man on earth, was also appointed as the first Prophet of God. He revealed His religion-Islam to him and enjoined him to convey and communicate it is him descendants: to teach them that Allah is One, the Creator, the Sustainer of the world that He is the Lord the universe and He alone should be Worshipped and obeyed; that to Him they will have to return one day and to Him alone they should appeal for help; that they should live good, pious, and righteous life in accordance with God's pleasure and that if they did so they would be blessed by God with goodly reward, and if they turned away from Him and disobeyed Him they would be losers here and in the hereafter and would be severely punished for this disbelief and disobedience.
Those of Adam's descendants who were good trod the right path shown to them by him, but those who were bad abandoned their father's teachings, and gradually drifted away into devious ways. Some began to worship the sun, the moon, and the stars; others took to the worship of trees, animals, and rivers. Some believed that air, water, fire health, and all the blessings and forces of Nature were each under the control of a different god and that each one of them should be propitiated by means of worship. In this way ignorance gave rise to many forms of polytheism and idolatry, and scores of religions were formulated. This was the age when Adam's progeny had spread fairly over the globe, and formed different races and nations. Every nation had made a different religion for itself, each with formalities and rituals of its own. God the One Lord and Creator of mankind and the universe was altogether forgotten. Not only that; Adam's descendants forgot even the way of life which God had revealed for them and which their great progenitor had taught them. They had followed their own devices. Every kind of evil custom grew, and all sorts of notions of ignorance spread them. They began to err in discerning right from wrong: many evils began to be considered right and many right things not only ignored but dubbed as wrong.
At this stage God began to raise prophets among every people, who preached Islam to them. Each one reminded his people of the lesson they had forgotten. They taught them God-worship, put an end to idol-worship and the practice of shirk, i.e. associating other deities with God, did away with all customs of ignorance, taught them the right way of living in accordance with God's pleasure, and gave them life-giving laws to be followed and enforced in society. God's true Prophets were raised in all countries: in every land and people. They all possessed one and the same religion the religion of Islam.
The concept of prophet-hood is found in the three great religions of Christianity, Judaism, and Islam. In Islam, however, it has a special status and significance. It is obligatory to specifically believe in the Messengers cited by Allah in the Qur'aan by name. They are twenty-five in all. Eighteen of them are mentioned in (Soorah Al-An'aam)
As for those Messengers who are not cited in the Qur'aan by name, it is obligatory to believe in them in general. Allah says; “Indeed, We have sent Messengers before you (O Muhammad); “some of them We have related to you their story and of some We have not related to you their story," [Soorah Al-Ghaafir (40): 78]. Another verse state; “Messengers We have mentioned to you before, and Messengers We have not mentioned to you." [Soorah Al-Nisa (4): 164]
Superiority of Some Messengers over the Others:
Messengers are of various ranks (amongst themselves). Allah says; "Those Messengers! We preferred some to others…" [Soorah al-Baqarah (2): 253] The most distinguished Messengers are the five 'Uulul-Azm' (the Strong Willed); 1. Prophet Nooh,
