Is the sweat of Janabah resulting from masturbation considered pure like the sweat of Janabah from a wet dream, and is it permissible to perform prayer with clothes that have the sweat of Janabah resulting from masturbation on them?

The jurists are in agreement regarding the purity of the sweat of a person in a state of major ritual impurity (junub), whether this impurity resulted from sexual intercourse, a wet dream, or masturbation. This has been authentically reported from Ibn 'Umar, Ibn 'Abbas, 'A'isha, and others. It is also the view of Malik, Al-Shafi'i, and the jurists of independent reasoning (Ahl al-Ra'y). They cited as evidence the Hadith of Abu Hurayrah: "Indeed, a believer does not become impure." They also cited the Hadith of the woman who dipped her hand, while in a state of major ritual impurity, into a vessel, whereupon the Prophet, peace and blessings be upon him, said: "Water does not become impure due to major ritual impurity." Therefore, there is no harm in praying in clothes that have been sweated in by a person in a state of major ritual impurity.
