At various places in the Quran and in different ways goodness is referred to as maruf (known), meaning that which is generally known. And evil has been called munkar (that which is unknown). In other words, vice is that which by instinct is unfamiliar to mankind. The innate nature (fitra) of man prompts him on what is wrong. Regardless of how many sins mankind may have committed or how many times they may have been involved in wrongdoing or in creating false philosophies, a vast majority of people never accepted established goodness to be evil, or evil to be good. The universal good has been recognized everywhere at all times. Collectively, the nations of the world have never agreed to a premise of accepting good to be evil or vice versa.

Humanism and humanity are both derived from the word man and have a higher moral connotation. This double meaning of ideas connected to man's name is a result of man's double nature, one of them originating from the earth and the other from heaven. The materialists always directed our attention to the external aspects of things. "The hand is not only an organ of work," writes Engels, "but also a product of it. Only through work ... the human hand attained that high degree of perfection in which it could produce Raffaello's paintings, Thorvaldsen's statues and Paganini's music."

Even those contemporary Jews, Christians, and Muslims who strive so hard to profess theologically "correct" beliefs about a sole, singular God who is incorporeal or infallible, ever-present or all-knowing, seem compelled to envision God in human form and to speak of God in human terms. Studies performed by a range of psychologists and cognitive scientists have shown that the most devout believers, when forced to communicate their thoughts about God, overwhelmingly treat God as though they were talking about some person they might have met on the street.

Mother of the Faithful, Aisha, may God be pleased with her, said, "God's Messenger, may God be pleased with him and his family, said, 'Anything invented outside the scope of our religion, by anyone, is rejected.'" Reported by Al-Bukhari and Muslim. In a report by Muslim, the text of the hadith is given as, "Any deed outside the scope of our religion, performed by anyone, is rejected."

Al-e-Imran (The House of Imran) Sura 3: Verse 139

"So lose not heart, nor feel distressed, for you shall gain mastery if you are true in faith."

Wahn means weakness, whether it concerns volition or action, or is of a physical or moral nature. In a hadith, we read that once the Prophet, peace be upon him, said to his companions that a time will come when Muslims will be reduced to 'froth and scum that rises above flood waters'. They asked about the reason for it whereupon he told them that they would have wahn in their hearts. 'What is wahn?' they asked him, and he replied, 'It is the love of the worldly life and the dislike of death' [Abu Dawud].
