Ulum al Qur'an
The Makkan Phase
The Makkan phase of the revelation lasted about 13 years, from the first revelation up to the hijra.
This phase is determined by the prime task of the Prophet to call people to Islam. The main themes of this call, based on the Qur'anic revelation are:
Allah and His unity (tawhid).
The coming resurrection and judgement.
Righteous conduct.
The role of the Prophet in this phase is in particular that of an announcer and Warner.
