What about the prostatic fluid that gets onto my clothes?' he said: 'it is sufficient for you to pour a handful of water on the part of your clothes wherever you see it has reached.'"

He came to Ubayy bin Ka'b accompanied by 'Umar. Ubayy came out to them and said: "I noticed some prostatic fluid, so I washed my penis and performed ablution. 'Umar said: "Is that sufficient?" He said: "Yes." He ('Umar) asked: "Did you hear that from the messenger of Allah?" He said: "Yes."

When the time for Maghrib (Sunset prayer) came, he got up, performed ablution, and offered prayer, then he went back to where he had been sitting. I said: 'May Allah improve you (i.e., your condition) Is it obligatory or Sunnah to perform ablution for every prayer?' He said: 'Did you notice that?' I said: 'Yes.' He said: 'No (it is not obligatory). If I perform ablution for Morning prayer I can perform all of the prayers with this ablution, so as long as I do not get impure. But I heard the Messenger of Allah say: "Whoever performs ablution while he is pure, he will have ten merits." So I wanted to earn the merits.'"

The Prophet was asked about the water basins located between Makkah and Al-Madinah, which were visited by wild animals, dogs and donkeys, and about using them for means of purification. He said: "Whatever they (the animals) have carried in their bellies is for them, and whatever is left over is for us, and is pure."

"We came to a pond in which there was the carcass of a donkey, so we refrained from using the water until the Messenger of Allah came to us and said: 'Water is not made impure by anything.' Then we drank from it and gave it to our animals to drink, and we carried some with us."

He said, "This is because the urine of the boy is of water and clay, but the urine of the girl is of flesh and blood." Then he said to me: "Did you understand?" I said: "No." He said: "When Allah the Most High created Adam, He created Eve (Hawwa') from his short rib, so the boy's urine is from water and clay, and the girl's urine is from flesh and blood." Then he said to me: "Did you understand?" I said: "Yes." He said: "May Allah cause you benefit from this."
