> Physiological effects of receiving revelation?

[Tema]

Are there many narrations which describe the effect that receiving revelation had on Prophet Muhammad (sallallaahu 'alayhi wasallam) in the physical sense?

Found an anti-slamic site. There certanly are, but to them, they are symptomes of epilepsy!!! So, we must go to His miracle # 1:the Qur'aan.

Not that new, Infidels did it in his lifetime. At least accusing him of being a genius poet had more sense; how can an insane person deliver an impeccable quran, and a set of scientific facts that over 1400 years was embraced and adopted by over 1.5 billion people as divine revelation and none were found wrong. Not to mention that the law and rulings that was brought were perfectly coherent and the epitome of justice by all standards.

Some nonsense is beneath the level requiring it to be refuted with evidence or detailed explanations.

The Revelation is always brought to me by an angel: sometimes it is delivered to me as the beating sound of the bell--and this is the hardest experience for me; but sometimes the angel appears to me in the shape of a human and speaks to me.” [40]
“Those who saw the Prophet (pbuh) in this state relate that his condition would change. Sometimes he would stay motionless as if some terribly heavy load was pressed on him and, even in the coldest day, drops of sweat would fall from his forehead” [41] At other times he would move his lips.
Ibn Sa'd says, "at the moment of inspiration, anxiety pressed upon the Prophet, and his countenance was troubled" [1]
"He fell to the ground like one intoxicated or overcome by sleep; and in the coldest day his forehead would be bedewed with large drops of perspiration. Inspiration descended unexpectedly, and without any previous warning." [2]
"Then Allah's Apostle returned with that experience; and the muscles between his neck and shoulders were trembling till he came upon Khadija (his wife) and said, "Cover me!" They covered him, and when the state of fear was over" [3] and [4]
