Muhammad Speaks with Khadijah and Waraqa
Then the Prophet repeated the words with a trembling heart. He returned to Khadijah from Mount Hira and said: "Wrap me up! Wrap me up!" She wrapped him in a garment until his fear was dispelled. He told Khadijah what had occurred and that he was becoming either a soothsayer or one smitten with madness. She replied: "Allah forbid! He will surely not let such a thing happen, for you speak the truth, you are faithful in trust, you bear the afflictions of the people, you spend in good works what you gain in trade, you are hospitable and you assist your fellow men. Have you seen anything terrible?"

Muhammad replied: 'Yes," and told her what he had seen. Whereupon, Khadijah said: "Rejoice, 0 dear husband and be cheerful. He in Whose hands stands Khadijah's life bears witness to the truth of this fact, that you will be the prophet to this people." Then she arose and went to her cousin Waraqa Ibn Naufal, who was old and blind and who knew the Scriptures of the Jews and the Christians, and is stated to have translated them into Arabic.

When she told him of what she had heard, he cried out: "Holy! Holy! Verily, this is the Namus (The Holy Spirit) who came to Moses. He will be the prophet of his people. Tell him this and bid him be brave of heart."

When the two men met subsequently in the street, the blind old student of the Jewish and Christian Scriptures spoke of his faith and trust: "I swear by Him in Whose hand Waraqa's life is, Allah has chosen you to be the prophet of this people. They will call you a liar, they will persecute you, they will banish you, they will fight against you. Oh, that I could live to those days. I would fight for these." And he kissed him on his forehead.

Muhammad Begins Preaching
The first vision was followed by a considerable period, during which Muhammad suffered much mental depression. The angel spoke to the grieved heart of hope and trust and of the bright future when he would see the people of the earth crowding into the one true faith. His destiny was unfolded to him when, wrapped in profound meditation, melancholy and sad, he felt himself called by a voice from heaven to arise and preach. 0 you (Muhammad) enveloped (in grments)! Arise and warn! And your Lord (Allah) magnify! Surah 74: 1-3

He arose and engaged himself in the work to which he was called. Khadijah was the first to accept his mission. She was to believe in the revelations, to abandon the idolatry of her people and to join him in purity of heart and in offering up prayers to Allah the Almighty.
