The Sunna of Mohammed
The Koran demands 91 times that Muslims imitate Mohammed in every way. These commands take two types—historical and the other is a direct command. The Meccan Koran is filled with examples of the previous “prophet/messengers” who had to be obeyed or Allah punished them. Moses is a historical example. There are only 5 direct commands to follow Mohammed in Mecca.
Then in Medina there are 86 verses with a direct command to obey and follow Mohammed. Why the increase? In Medina Mohammed was a political leader and needed total command in this world, not the next.
