Sa'id ibn al-Musayyib سعيد بن المسيب بن حزن أبو محمد القرشي · The Book on Marriage

"We went with Allah's Messenger, while we were young men who had nothing. He said: 'O young men! You should marry, for indeed it helps in lowering the gaze and protecting the private parts. Whoever among you is not able to marry, then let him fast, for indeed fasting will diminish his sexual desire."

the Prophet said: "Whoever believes in Allah and the Last Day, then he does not levy his water on someone else's child."
