The Muhammadan Call could be divided into two phases distinctively demarcated:
- The Makkan phase: nearly thirteen years.
- The Madeenese phase: fully ten years.
The Makkan phase can be divided into three stages:
- The stage of the secret Call: three years.
- The stage of the proclamation of the Call in Makkah: from the beginning of the fourth year of Prophethood to almost the end of the tenth year.
- The stage of the call to Islaam and propagating it beyond Makkah: it lasted from the end of tenth year of the Prophethood until Muhammad’s (صلى الله علیه وسلم) emigration to Madeenah.
