In most history books of Shiite and Sunni Islam, there are two titles: "secret invitation" and "public invitation". The well-known view of historians of Islamic history on the method of the Prophet inviting people to Islam is that it was not his mission to invite everyone after the Bi’ tha and therefore, for up to three years, he invited the hearts ready to accept the truth secretly and privately to Islam. Then, in the second stage of his mission, with the revelation of verse 214 of Surah Al-Shu’ ara, he invited his relatives, and then in the third stage of his mission, with the revelation of verse 94 of Surah Al-Hijr, his mission was to invite the public people. This popular theory is based on historical news and interpretive narratives. However, it leads to many ambiguities and is not compatible with the context of the verses, the purpose of the related surahs and the revelation of the Qur’ an. If we go through the analysis of this theory based on the three principles of presenting narrations on the Qur’ an, the method of Tanzili interpretation (the interpretation of the Qur’ an based on the order of the revelation of Suarahs) and lexicography of verses and narrations, we will see that the Prophet preached monotheism from the beginning, and about six years after the Bi’ tha, he was commissioned to establish the social status of the mission and to officially announce the Muslim organization. This study has been carried out by descriptiveanalytical method and using library documents, it shows that contrary to what is known about the stages of the development of Islam in the age of revelation, which divides the history of Islam in the Meccan era into two periods of secret and public invitation, the invitation of the Prophet has been public since the beginning of his mission.
