Due to the significance of the beliefs, the Qur’an has developed arguments about them in chapters which were revealed in Makkah. Actually, the chapters which were revealed during the three first years of the revelation are full of descriptions about the Islamic credos.
As I have searched, the chapters which are revealed to the Prophet (P) in Makkah particularly those are revealed during the three first years of revelation consist of many verses that explain Islamic beliefs and creeds. Indeed, believing in Allah (SWT) and believing in the Day of Judgment are the most important beliefs of Islam to which every chapters (Surrah) of the Qur’an devote some verses to explain and define them. The first forty seven chapters, according to the order of the Revelation, or generally the eighty six chapters which were revealed in Makkah contain many basic and logical arguments and explanations about Islamic beliefs.
