Islam History 5 / Muhammad was so worried that he was demon possessed or losing his sanity
At first Muhammad was so worried that he was demon possessed or losing his sanity that he was going to jump off a cliff. On his way to do this he had another revelation telling him not to kill himself since he had been truly called of God. Still it was his wife and friends who convinced him these were from God. She encouraged him to listen to the revelations.
Because of the manner of these revelations, the people of Mecca called Muhammad “a poet possessed” and a medium or soothsayer. This is recorded several places in the Koran. There are at least 11 places where the Koran tries to defend Muhammad from charges of being demon possessed. Some in Mecca called him a lunatic and said he needed a doctor.
“…the wrongdoers declare: ‘The man you follow is surely bewitched.” Sura 17:47 “And the wrongdoers say: ‘The man you follow is surely bewitched.” Sura 25:8
“Thus shall We deal with the evil-doers for when they were told: ‘There is no deity but God,’ they replied with scorn: ‘Are we to renounce our gods for the sake of a mad poet?'” Sura 37:35
“Therefore give warning. By the grace of God, you are neither a soothsayer nor madman… Do they say: He [Muhammad] has invented it himself? Indeed, they have no faith. Let them produce a scripture like it, if what they say be true!” Sura 52:29-34
“By the pen and what they [angels] write, you [Muhammad] are not mad: thanks to the favor of your Lord! A lasting recompense awaits you, for yours is a sublime nature. You shall before long see — as they will see — which of you is mad.” Sura 68:1-2
“No, your compatriot Muhammad] is not mad. He saw him [Gabriel) on the clear horizon.” Sura 81:22
