Zombie: Patience my friend. I've been busy with college and not able to post the information.
Waraqa said, "This is the same Namus (i.e., Gabriel, the Angel who keeps the secrets) whom Allah had sent to Moses. I wish I were young and could live up to the time when your people would turn you out." Allah's Apostle asked, "Will they turn me out?" Waraqa replied in the affirmative and said: "Never did a man come with something similar to what you have brought but was treated with hostility. If I should remain alive till the day when you will be turned out then I would support you strongly." But after a few days Waraqa died and the Divine Inspiration was also paused for a while and the Prophet became so sad as we have heard that he intended several times to throw himself from the tops of high mountains and every time he went up the top of a mountain in order to throw himself down, Gabriel would appear before him and say, "O Muhammad! You are indeed Allah's Apostle in truth" whereupon his heart would become quiet and he would calm down and would return home. And whenever the period of the coming of the inspiration used to become long, he would do as before, but when he used to reach the top of a mountain, Gabriel would appear before him and say to him what he had said before. (Ibn 'Abbas said regarding the meaning of: 'He it is that Cleaves the daybreak (from the darkness)' (6.96) that Al-Asbah. means the light of the sun during the day and the light of the moon at night). Quoted from the Sahih (authentic) Hadith (traditions) of Bukhari, [2], Volume 9, number 111
Additional details from Ibn Ishaq's "Sirat Rasulallah" from Guillaume's translation, "The Life of Muhammad", [3], page 106. Words in [ ] type brackets are mine. Words in ( ) brackets are the author's.
"So I [Muhammad] read it, and he [Gabriel] departed from me. And I awoke from my sleep, and it was though these words were written on my heart. (Tabari: Now none of God's creatures was more hateful to me than an (ecstatic) poet or a man possessed: I could not even look at them. I thought, Woe is me poet or possessed - Never shall Quraysh say this of me! I will go to the top of the mountain and throw myself down that I may kill myself and gain rest. So I went forth to do so and then) when I was midway on the mountain, I heard a voice from heaven saying "O Muhammad! thou are the apostle of God and I am Gabriel."
In "Muhammad at Mecca", by W. M. Watt, [6], pages 40, 41, there are also references that detail Muhammad's suicidal thoughts. Watt quotes from az-Zuhri's material
"He (Muhammad) said, I had been meditating throwing myself from a mountain crag, but while I was so meditating, he appeared to me and said, "O Muhammad, I am Gabriel, and thou are the Messenger of God."....
Az-Zuhri said: "There was a gap for a time in the revelation to the Messenger of God and he was very sorrowful. He started going early to the tops of the mountains to throw himself down from them. But whenever he reached the summit of a mountain, Gabriel would appear to him and say, "Thou are the Prophet of God."
