The Messenger of Allah ﷺ said, "Young men of Quraysh, do not commit fornication. Guard your private parts. Whoever guards his private parts will have Paradise."
قال رسول الله ﷺ: يا شباب قريش! لا تزنوا، احفظوا فروجكم، ألا من حفظ فرجه فله الجنة.

Bazzar narrated it in Kashf Astar (1401), and Tabarani in Al-Kabir (12/165) and Al-Awsat, from the hadith of Muslim bin Ibrahim, who said, Shaddad bin Saeed narrated to us, who said, Saeed Jareeri narrated to us, from Abu Nadra, from Ibn Abbas, and he related it, the wording being that of Bazzar.Its chain is hasan because of Shaddad bin Saeed, for there is disagreement about him, though his hadith is hasan when he does not contradict others, and he is among the narrators used by Muslim. Haythami said in Al-Majmu (4/252), "His narrators are the narrators of the Sahih." Saeed Jareeri is Ibn Iyas, Abu Masud Basri. Yahya bin Main and Nasai gave an unqualified affirmation of his reliability, but Abu Hatim said, "His memory deteriorated before his death. So whoever wrote from him in his earlier period, that is sound, and his hadith is hasan." Ibn Hibban said, "He had become confused three years before his death." He said, "Yahya Qattan saw him while he was in that confused state, and his confusion was not severe."
