When the Holy Prophet returned home he was highly agitated and most nervous. He told of the occurrence in the cave to his wife Khadija. She consulted her cousin Waraqa b Naufal who was versed in religious lore. Waraqa said that the angel who had appeared before Muhammad (peace be upon him) was the same angel who had appeared before Abraham, Moses and other prophets. Waraqa added that the visiting of the angel was a great event, and she should rejoice that her husband had been chosen by the Almighty God as His Messenger. When Khadija told Muhammad (peace be on him) what Waraqa had said, Muhammad (peace be on him) said that the burden of prophethood would be too heavy for him to bear, and he did not know who would accept conversion to the new faith at his hand. Khadija consoled him and said that the Almighty who had chosen him as His Messenger would Himself guide him in fulfilling His mission of prophethood. Khadija offered herself as the first person to owe allegiance to Muhammad (peace be on him) as the prophet of God. When Ali came to know of the conversion of Khadija he hastened to offer his allegiance to the Holy Prophet. Ali was the first among the youth to be converted to Islam. In some books it is written that when Muhammad (peace be upon him) invited Ali to the new faith, he showed some hesitation and said that he would consult Abu Talib in the first instance. This version of what happened is far from the truth. There was no hesitation on the part of Ali in accepting the truth. Ali had indeed been longing for the day when the call from the Almighty would come and when the call came he was so much overwhelmed with joy that there could be no question of any hesitation. The acceptance of the new faith on the part of Ali was spontaneous and without any hesitation, for Ali had the firm conviction that Muhammad (peace be upon him) was the true prophet of God.
