When sins are mentioned, many people only think of corporeal sins, in oblivion to the graver sins, which are the sins of the hearts. Shaykhul-Islaam Ibn Taymiyyah said: “Know that when sins are mentioned, what comes first to many people’s minds are Zina (fornication or adultery), theft, and the like, believing that it is beneath a noble person to commit them.
However, these poor people do not know that most rational human beings do not steal nor commit Zina, even if they were living in a state of Jaahiliyyah (the pre-Islamic era of ignorance) and disbelief in Allah.
There are many branching kinds of sins, such as those related to misguidance in matters of faith, religious innovations which are of the same nature of arrogantly causing mischief on earth, (blameworthy) pride, vanity, envy, self-conceit, and Riyaa’ (doing good to impress people rather than to please Allah).
