The source books that have come down to us do not throw sufficient light on the wisdom of migration to Abyssinia. It was the year 615 C.E. and by this time Ali had come of age. Ali was an embodiment of courage and bravery. When the Quraish subjected the poorer sections of the Muslims to hardship, Ali asked the permission of the Holy Prophet to retaliate, and fight against the Quraish who used force against the Muslims. There were some other young men among the Muslims who were of the same view as Ali, and who were prepared to fight against the Quraish, and die for the defense of Islam. The Holy Prophet felt that with such a meager number of Muslims, any headlong-armed conflict between the Muslims and the Quraish was likely to be against their interests. The migration to Abyssinia was undertaken not because of the fear of the Quraish, it was undertaken to restraining the Muslims from open war with the Quraish. The Holy Prophet also felt that if the Muslims established a settlement outside Arabia that would help in the promotion of Islam in other parts of the world. A Muslim settlement along the borders of Arabia was likely to be a source of strength to the Muslims in Arabia. The Muslims who migrated to Abyssinia were likely to have better opportunities for economic betterment and that would work to the advantage of the Muslim community as a whole. That would also help the Muslims in Arabia strengthen their trade relations with Abyssinia. The Quraish were alive to these advantages that were likely to accrue to them as a trestle of the migration of a batch of the Muslims to Abyssinia. Accordingly the Quraish sent a delegation to Abyssinia to prevail on the Negus of Abyssinia to expel the Muslims from his country. The Negus invited the Muslims to his court and asked them to explain what was the faith they had adopted. Jafar, the brother of Ali, acting as the spokesman of the Muslims presented such a splendid picture of Islam that the Negus was much impressed, and he refused to oblige the Quraish.
The discomfiture of the Quraish mission to Abyssinia gave a great setback to the cause of the Quraish. They had failed to convince the Negus of the genuineness of their cause. On the other hand, the Muslims had succeeded in impressing the Negus and he had agreed to patronize them. Thus in the first round of the battle between the truth and falsehood, falsehood suffered defeat while the truth scored a victory. Although we are not very definite as to what role Ali played in the battle, but there are strong grounds to believe that he played an important part in winning the battle.
