Is a person held accountable for diseases of the heart that overcome him? Are all diseases of the heart major sins? And is he held accountable for all of them?

Ibn al-Qayyim divided heart diseases into two types: The first type is not immediately painful to its possessor, such as ignorance, doubts (shubuhat), and desires (shahawat). This is the most dangerous type, and its cure lies with the Messengers and their followers. The second type is immediately painful, such such as anxiety and sorrow, and it may be alleviated by natural remedies. This type alone does not cause its possessor's misery after death. Ibn al-Qayyim clarified that heart diseases that can only be cured by faith-based remedies (such as doubts and desires) lead to perpetual misery and torment if left untreated. All heart diseases stem from following one's whims (hawa), and a servant will be held accountable for them, regardless of whether they are accompanied by physical actions or not. As for whether they are major or minor sins, examples include disbelief (kufr), doubt (shakk), hypocrisy (nifaq), polytheism (shirk), and their derivatives. Disobedience is of two types: major sins such as "showing off (riya'), self-admiration ('ujb), arrogance (kibr), and envy (hasad)," and minor sins such as "desiring forbidden things and wishing for them."
