Muhammad’s first teachings emphasized his belief in one transcendent, but personal God, the Last Judgment, and social and economic justice. Allah, he declared had sent prophets throughout history, but, having failed to reform, those nations had been destroyed. Muhammad proclaimed that his message, the Qur’an, was to be the last revealed book and himself to be the last of the prophets. The angel Gabriel told him that it was his duty to spread word of the oneness of Allah and of the existence of Judgment Day and resurrection. To escape the divine wrath and eternal fire, the sinner must repent and throw himself upon the mercy of god, a submission (islam) that gave its name to the religion. Muslims are suppose to pray facing the Kaaba five times a day.
Major points of Muhammad’s public teaching:
1. There was only one God (Allah) and all should submit to him.
2. All believers in God were equal.
3. The rich should share with the poor.
4. People should live righteously.
5. All people would be subjected to a Judgment Day.
The Prophet’s companions credited Muhammad with miracles although the Qur’an explicitly denies that he performed any. These miracles are:
1. He passed through the seven levels of heaven in the “Night’s Journey.”
2. He brought forth a spring in Mecca. (source : www.geocities.com)
