Abul Fida has narrated from Ibn Ishaq that Abu Bakr used to cultivate the company of the Prophet before his being vested by the office of prophethood and was so much aware of his truthfulness, trustworthiness and honesty that he knew him to be immune from attributing falsehood to people, far be it from him that he should attribute falsehood to Almighty God.[^3] Most Muslims in the early period of Islam embraced faith in this way since they were satisfied with the truthfulness and honesty of the Prophet and they knew that he never resorted to lying; therefore they believed his claim of prophethood and messengership with perfect certainty and embraced faith.

In the near future, we would discuss about the prominent and magnetic personality of the Messenger of Allah (S) and his good manners and praiseworthy qualities. Second Method Recognizing the veracity of a religion and to be sure that it is heavenly, and verification of the message brought by it, can be undertaken through study and investigation in the text of its belief and ethical laws.

If the beliefs proposed by it possess qualities like: compatibility with reason, and that it is opposed to superstitions, it is comprehensive and reliever of the social and moral difficulties of people, it calls people to good morals and character and restrains them from social and moral corruption, it would be known that this religion is true and that it is heavenly, and that it has really come from Almighty God and the true prophets of God.

But if the beliefs of that religion are dubious and invalid and its laws are weak and baseless, and they cannot solve social and moral problems, it would be known that its claimant is a liar and his religion is futile and invalid. Some Muslims in the early period of Islam embraced faith in this same way.

After study and contemplation about the beliefs and laws of Islam, they concluded that the proposal and compilation of such lofty and hundred percent correct and perfect beliefs could not be possible through an uneducated person, and also that they should be announced in a backward society mired in idol worship and moral decadence of the Arabian Peninsula; on the contrary they should be from Almighty Allah.

At this point we shall mention some examples of this: Amr ibn Ambasa says: In the early period of Islam, I came to the Messenger of Allah (S) at a time when he lived in fear of his life. I asked: Who are you? He replied: I am a messenger. I asked: Whose messenger?
