穆罕默德想把他的新宗教传播给其他人。由于穆罕默德坚持放弃多神教的邪教，这使他与他人发生冲突。因此，他必须找到一个地方让人们跟随他。他在麦地那找到了他的支持者。那里的人们已经准备好听他的宗教信息，并把他当作他们社区的领袖。尽管穆斯林在麦地那取得了成功，他们还是觉得受到了Quraysh的威胁。默罕默德和他的追随者在巴德尔战役中杀死了他们中的49人。由于他的伟大胜利，穆罕默德获得了新的追随者。穆罕默德死后，哈里发继续跟随穆罕默德的脚步。他们征服了更多的领土。拜占庭帝国和萨珊王朝促成了穆斯林的迅速扩张。由于彼此之间的战争已经削弱了帝国的势力，穆斯林很容易就征服了这两个地区，并将伊斯兰统治延伸到更多的领土。而且，就像你提到的，穆斯林已经是战争的专家了。他们打败了两个帝国的军队没有问题。
加拿大农业论文代写:穆罕默德
Muhammad wanted to spread his new religion to others. Because of Muhammad’s insistence of abandoning polytheistic cults, it brought him conflict with other people. Therefore, he had to find a place where people would follow him. He found his supporters in Medina. The people there were ready to listen to his religious message and to regard him as their leader in the community. Even though Muslims were successful at Medina, they felt threatened by the Quraysh. Muhammad and his followers killed forty-nine of the Meccan enemy at the battle of Badr. Because of his great victory, Muhammad was able to gain new followers. After Muhammad’s death, the caliphs continued and followed Muhammad’s footsteps. They conquered more territories. The Byzantine and the Sassanid empires contributed to the quick expansion of the Muslims. Because of being already weakened empires due to fighting each other, the Muslims easily conquered both territories and extended the Islamic rule into more territories. Also, like you mentioned, the Muslims were already experts to warfare. They had no problem defeating the armies that the two empires had.
