The Book of Purification
كتاب الطهارة
Chapter 32: The ruling on semen
I stayed in the house of 'A'isha and had a wet dream (and perceived its effect on my garment), so (in the morning) I dipped both (the clothes) in water. This (act of mine) was watched by a maid-servant of A'isha and she informed her. She (Hadrat A'isha) sent me a message: Whatprompted you to act like this with your clothes? He (the narrator) said: I told that I saw in a dream what a sleeper sees. She said: Did you find (any mark of the fluid) on your clothes? I said: No. She said: Had you found anything you should have washed it. Incase I found that (semen) on the garment of the Messenger of Allah (ﷺ) dried up, I scraped it off with my nails.
Chapter 33: The impurity of blood and how to wash it
A woman came to the Messenger of Allah (ﷺ) and said: What should one do if the blood of menses smears the garment of one amongst us? He (the Holy Prophet) replied: She should scrape it, then rub it with water, then pour water over it and then offer prayer in it.
This tradition is narrated by Abu Kuraib, Ibn Numair, Abu Tahir, Ibn Wahb, Yahya b. 'Abdullah b. Salim, Malik b. Anas, 'Amr b. Harith on the authority of Hisham b. 'Urwa, with the same chain of transmitters like one transmitted by Yahya b. Sa'id like the above-mentioned.
Chapter 34: The evidence that urine is impure and the obligation to take precautions concerning it
The Messenger of Allah (ﷺ) happened to pass by two graves and said: They (their occupants) are being tormented, but they are not tormented for a grievous sin. One of them carried tales and the other did not keep himself safe from being defiled by urine. He then called for a fresh twig and split it into two parts, and planted them on each grave and then said: Perhaps, their punishment way be mitigated as long as these twigs remain fresh.
" The other did not keep himself safe from being defiled by urine."
