Abdullah b. Shihab al-Khaulani reported:
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.
