Does the Hadith: "I certainly know peoples from my Ummah who will come on the Day of Resurrection with good deeds like the white mountains of Tihamah, and Allah, the Mighty and Exalted, will make them like scattered dust… but they are a people who, when they are alone with Allah’s prohibitions, violate them," apply to those who practice masturbation?

This hadith is specific to those who feign piety while secretly violating sacred prohibitions, as mentioned by Al-Haytami in "Az-Zawajir." The warning in the hadith applies to those who outwardly display acts of obedience before people but do not observe Allah in solitude. As for someone who performs acts of obedience sincerely and occasionally falls into sin, keeping it concealed, we hope that this warning does not include them.
