Imam Bukhari narrates: Qabisah ibn 'Uqbah narrated to us, he said: Sufyan narrated to us, from Abi al-Zinad, from al-A'raj, from Abu Hurairah (may Allāh be pleased with him), he said that

the Prophet ﷺ forbade two kinds of sale: al-lamas and al-nibadh, and forbade ishtimal-e-sammā and sitting in a single cloth in the manner of ihtibā.
