It is truly pleasant to know and realize the degree of truth that is communicated in revelation. God says in the Holy Quran after Adam and Eve fell into the temptations of the devil (and ate from the forbidden tree):
"And God said, "Get ye all down hence, the one of you a foe unto the other. Hereafter shall guidance come unto you from me; And whoso followeth my guidance shall not err, and shall not be wretched: But whoso turneth away from my monition, his truly shall be a life of misery: And We will assemble him with others on the day of Resurrection, blind."
