[Machine] If one of you scratches his skin, he should not wipe it with his saliva, as it is not pure. I mentioned that to Ibrahim and he said, "wipe it with water, as Salman intended." Allah knows best that saliva does not purify the outward blood by scratching. As for the hadith of Ammar ibn Yasir, the Prophet said to him, "O Ammar, your nasal discharge and tears are only equivalent to the water in your water container. You only wash your clothes from urine, feces, semen, blood, and vomit. This is a false statement with no basis."
