What is the ruling on masturbation, or "hand marriage," and have any hadiths been narrated about it from the Messenger of Allah, peace and blessings be upon him, and how can one be cured of it?

Masturbation is forbidden according to most scholars, and this is the preponderant view. There is no authentic, established hadith (definition) reported from the Prophet, peace be upon him, regarding it. What has been narrated in this regard is either fabricated, has no basis, or lacks an authentic chain of transmission. Examples include the hadith: "May Allah curse him who marries his hand," and a report from Ata' who said: "I heard that a people will be resurrected on the Day of Judgment with their hands pregnant, and I think they are these people," and a report from Sa'id ibn Jubayr who said: "Allah punished a nation who played with their private parts."

In conclusion, no authentic hadith has been established regarding masturbation, despite it being forbidden based on other stronger evidences, the most powerful of which is the noble verse: ﴿But whoever seeks beyond that, then those are the transgressors﴾.
