Islam first emerged in the Arabian Peninsula. The word Islam means “universal submission to God”. There were several reasons for the rapid and successful spread of Islam in the Arabian Peninsula. The primary cause of the successful spread of Islam in the Arabian Peninsula was Muhammad's ability to inspire almost limitless devotion in those with whom he came into close contact. The second cause of the rapid spread of Islam was the superficiality and inadequacy of the paganism of the Arabs, who actually attached little importance to their ancient religion. The third reason for the rapid spread of Islam in Arabia was that after the Apostasy all tribes accepted Islam and the previous conflict between religion and tribal loyalty disappeared. The fourth reason was that as soon as the war against Byzantium and Persia began, all objections against Islam disappeared. The fifth reason for the rapid spread of Islam in Arabia was that after the death of Muhammad there was nothing as successful as his success. The sixth reason for the rapid success of Islam in Arabia was its perfect adaptation to the people and the time. It was essentially an Arab religion. The Quran was revealed in Arabic, which the Arabs thought was the language used by God (Glubb 381-384). The Prophet Muhammad was the founder of Islam. Muhammad was recognized and recognized by the Jews, at the time of his birth, and later by the Abyssinian Christians as the apostle of God (Peter 133). Muhammad's life and achievements would forever influence the spiritual, political, and ethical outlook of Muslims (Armstrong 23). Muhammad was called to be the Messenger and Prophet of God around the age of forty, although he reported that some time before the angel Gabriel first... middle of paper... eek refuge with the prophet of God, that God him bless and save him. Flee from him, place yourself under his protection and ask him to intercede for you before God, and God will accept this intercession. This is my opinion." When Kankan Musa asked one of his shaykhs (elders) to choose the day of his departure, the shaykh told him: “you should wait for the Sabbath which falls on the twelfth day of the month. Depart that day and you will not die before returning safely to your residence, pleasing God.” He waited nine months to begin his pilgrimage until a Saturday and the 12th of the month coincided. From then on, Mail travelers believed that it was lucky to go on a pilgrimage to Mecca on Saturday, i.e. the 12th of the month (Overfield/Andrew 229). When he left for his pilgrimage he had 8,000 men with him (Overfield Andrea 230).
