Musnad Abu Ya'la al-Mawsili 45:14

Muhammad ibn Marzuq narrated to us, Zafir ibn al-Salt narrated to us, from al-Harith ibn Umayr, from Shaddad, from Abu Talhah, that the Messenger of Allah (may Allah bless him and grant him peace) said: "O youth of Quraysh, do not commit adultery. Whoever preserves his youth, for him is Paradise."
