Riyad as-Salihin 4:17

Hudhaifah bin Al-Yaman (May Allah be pleased with him) reported:

The Messenger of Allah curses the one who sits in the middle of people's circle. [Abu Dawud] . A man sat in the middle of a circle so Hudhaifah (May Allah be pleased with him) said: Cursed upon the tongue of Muhammad (ﷺ) or [he said] Allah has cursed upon the tongue of Muhammad (ﷺ) he who sits in the middle of the circle [of a gathering].
