Imam Ali (radiy-Allahu anh) said: “Muslims believe in the next world. Disbelievers without a heavenly book deny it. If there weren’t a rising, disbelievers would not gain anything and Muslims would not suffer any harm. But since what disbelievers believe will not happen, they will suffer eternal torment.” Islamic scholars prove their words true and respond to the attacks of disbelievers through reason, knowledge and science. Could resurrection be denied if Muslims did not prove their words to be true? Even if being under eternal torment were only a probability, whose wisdom would take the risk of it? Nevertheless, torment in the next world is not only a probability, but an obvious fact. Then, it is unwise not to believe.
