Which hadith applies to someone who habitually commits sins in private and does not speak of them: "There will come on the Day of Resurrection people with good deeds like mountains, and Allah will make them scattered dust." It was said: "Describe them to us, O Messenger of Allah." He said: "They are people who, when they are alone with the unlawful acts of Allah, they commit them..." or "All of my Ummah are forgiven except al-mujahiroon (those who publicize their sins)..."?

He who openly commits a sin before people adds another sin to his sin, for he has committed two forbidden acts: displaying disobedience and behaving like the dissolute. Although the one who commits a sin in secret is sinful and punishable, the one who publicizes it is worse in sin and more severe in punishment. Openly committing a sin shows disdain for the rights of Allah and His Messenger, and for the righteous believers. It is also a form of defiance towards them, whereas concealment protects one from disdain and punishment. The disobedient person who conceals his sin out of shame and modesty before Allah and people is less culpable than the one who publicizes it. As for the one who violates Allah's prohibitions when alone and only observes people, the Prophet, peace and blessings be upon him, warned against him in the hadith: "I certainly know people from my nation who will come on the Day of Resurrection with good deeds like the white mountains of Tihamah, and Allah will make them scattered dust. Thawban said: O Messenger of Allah, describe them to us, make them clear to us, so that we do not become among them unknowingly. He said: Indeed, they are your brothers and from your own kind, and they pray at night as you do, but they are people who, when they are alone with Allah's prohibitions, violate them." Therefore, one must abstain from sins, repent to Allah, and observe Him in secret and in public.
