Biography of Sulayt
Us S: Sulayt is not attributed, mentioned by al-Hasan b. Sufyan in al-Wahdan.
He narrated with his isnad, from Isma'il b. Muslim, from al-Hasan, from Sulayt, who said: I reached the Messenger of Allah ﷺ while he was sitting with his Companions.
I seem to be looking at the whiteness of his ring in the darkness of the night, so I heard him say: 'The Muslim is the brother of the Muslim, he should not oppress him, nor should he abandon him, piety is here,' and he pointed with his hand to his chest.
He was narrated by Abu Na'im, and Abu Musa.
