Re-Examination of the Beginning Month of the Lunar Year Based on Quranic-Hadith Culture and Historical Sources

The lunar year is based on the migration of the Prophet (pbuh) from Mecca to Medina. There are two popular views on the month of the beginning of the lunar year, one of which considers the month of Muharram and the other the month of Rabīʿul Awwal as the first month. Based on research, both views seek to prove their point by relying on historical accounts. But it seems that the historical argument, because of the contradictory reports and the flaws in both views, cannot be useful in determining the first lunar month of certainty and even certainty. In this article, with a descriptive-analytical approach, with a new look at the issue and relying on Islamic culture based on the Qur'an and hadiths, as well as presenting different reasons such as the signing of the Arab calendar by the Prophet (pbuh) and the rule of grace, it is proved was the Holy Prophet (pbuh) and signed Muharram as the first month of Hijrī history.
