Umm Qais daughter of Mihsan told how she brought a young son of hers who was not yet weaned to God’s messenger. He set him on his lap, and the child passed water on his garment; so he called for water and sprinkled it, but did not wash it.
Sulaiman b. Yasir said that he asked ‘A’isha about the prostatic fluid which gets on to a garment, and she replied, “I used to wash it from the garment at God's messenger, and he would go out to prayer with the mark of the washing on his garment."
