Abdur-Razzaq عبد الرزاق بن همام · 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."
