Each day a new aspect of his character would beam out of his noble person and I would accept it and follow it as a command." (Nahju'1-balaghah) Ten years in the company of the Holy Prophet had kept him so close and inseparable, that he was one with him in character, knowledge, self-sacrifice, forbearance, bravery, kindness, generosity, oratory and eloquence. From his very infancy, he prostrated before God along with the Holy Prophet.
As he himself said: "I was the first to pray to God along with the Holy Prophet." "Ali preserved in the footsteps of the Holy Prophet," says al-Mas'udi, "all along his childhood." Allah created him pure and holy and kept him steadfast on the right path.
Though 'Ali is indisputably the first to embrace Islam when the Holy Prophet called upon his listeners to do so, yet by the very fact that since his infancy he was brought up by the Holy Prophet and followed him in every action and deed including prostration before Allah, he can be said to be born a Muslim, just like the Holy Prophet himself. `Ali, at all times, accompanied the Holy Prophet to help and protect him from his enemies.
He used to write down the verses of the Holy Qur'an and discuss them with the Prophet as soon as they were revealed by the Holy Messenger, the Gabriel. He was so closely associated with the Holy Prophet that as soon as a verse was revealed to him during the day or night, Ali was the first to hear it. The Holy Prophet has said of `Ali: O `Ali, you are my brother in this world as well as in the Hereafter. I am the city of knowledge and 'Ali is the gate. Nobody knows 'Ali except Allah and I.
Nobody know me except Allah and `Ali. If you want to see the knowledge of Adam, the piety of Noah, the devotion of Abraham, the awe of Moses, and the service and abstinence of Christ, look at the bright face of `Ali. When the Holy Prophet reached Yathrib (Medina) and met his followers who had come from Mecca at his call, he immediately appointed for each such followers a person from the people of Yathrib known as Ansar (Helpers), who had accepted his prophethood, to be a brother to him.
His appointment of brothers was a great act of help for the refugees known as Muhajirun (Emigrants), who left their home and come to Yathrib. He made brothers of people who followed the same trade so that the Muhajirun could be usefully employed immediately.
