183 – (The Messenger of Allah, peace and blessings be upon him, said to Alī ibn Abī Tālib: “O Alī, do not follow one glance with another. The first is permitted for you, but not the second.” Narrated by Ahmad, Abū Dāwūd, and al-Tirmidhī.) p. 149

Authentic. Al-Bukhārī (4/170, 254), Muslim (8/52), and Ahmad (2/276) transmitted it by way of Ibn Abbās, who said: “I have seen nothing more closely resembling the lesser sins than what Abū Hurayrah reported from the Prophet, peace and blessings be upon him: ‘Allah has decreed for the son of Adam his share of fornication, which he will inevitably encounter. The fornication of the eye is looking, the fornication of the tongue is speaking, and the soul yearns and desires; the private parts then either confirm all of that or belie it.’” It also has other chains from Abū Hurayrah in Muslim and al-Musnad (2/343, 344, 372, 411, 528, 535, 536). It also has a corroborating report there (1/412) from Ibn Masūd. Al-Mundhirī (3/56) declared it authentic, and its chain is sound.

185 – (He, peace and blessings be upon him, said: “A man must not look at another man’s private parts, nor a woman at another woman’s private parts. A man must not be in direct bodily contact with another man beneath a single covering, nor a woman with another woman beneath a single covering.” Narrated by Muslim, Ahmad, Abū Dāwūd, and al-Tirmidhī.) p. 150
