Why did Muslims delay? Why do others come forward?

The reasons for the advancement of the Muslims were due in their entirety to the Islamic religion that had appeared new in the Arabian Peninsula and was filled with Arab tribes. With its guidance, they transformed from division to unity, from pre-Islamic times to civilization, and from worshiping idols to worshiping the One and Only One, and they conquered half of the earth in half. century, and had it not been for the dispute that had returned between them since the end of the caliphate of Uthman and in the caliphate of Ali - may God be pleased with them - they would have completed the conquest of the world, and no one would have stood in their way.However, those conquests that they conquered in half a century or two-thirds of a century - despite the wars caused by Muawiyah''s opposition to Ali and the wars that took place between the Umayyads and Ibn al-Zubayr - astonished the minds of rational people and historians, puzzled the great conquerors, and amazed Napoleon Bonaparte, the greatest of them, who admired Muhammad and Omar. And many of the heroes of Islam, and his soul told him when he was in Egypt that he would adopt Islam as his religion.
