The following short book discusses understanding the difference between having hope in obtaining good and wishful thinking. This discussion is based on Chapter 2 Al Baqarah, Verses 78-82 of the Holy Quran:

“And among them [people of the book] are unlettered ones who do not know the Scripture [the Torah and Bible] except [indulging in] wishful thinking, but they are only assuming. So woe to those who write the "scripture" with their own hands, then say, "This is from Allah," in order to exchange it for a small price. Woe to them for what their hands have written and woe to them for what they earn. And they [the people of the book] say, "Never will the Fire touch us, except for [a few] numbered days." Say, "Have you taken a covenant with Allah? For Allah will never break His covenant. Or do you say about Allah that which you do not know?” Yes, [on the contrary], whoever earns evil and his sin has encompassed him - those are the companions of the Fire; they will abide therein eternally. But they who believe and do righteous deeds - those are the companions of Paradise; they will abide therein eternally.”
