Hadith 17:260
Muhammad ibn Bishr and Abdullah ibn Numayr narrated to us, they said: Abdullah narrated to us, from Nafi’, from Ibn Umar, who said: The Messenger of Allah (peace be upon him) said: "When there are three, let not two whisper to each other excluding the other." And Ibn Numayr said: "Let them not converse privately."
