Uthman bin 'Asim bin Husayn عثمان بن عاصم بن حصين أبو حصين · The Book of Purification

"I was a man who had a lot of prostatic discharge, and the daughter of the Prophet (ﷺ) was married to me, so I felt shy to ask him (about that). I said to a man who was sitting beside me: 'Ask him,' so he asked him and he said: 'Perform Wudu' for that.'"
