وعن ابن عمر رضي الله عنهما
أن رسول الله صلى الله عليه وسلم قال: «إذا كانوا ثلاثة فلا يتناجى اثنان دون الثالث»
The Messenger of Allah (sallallahu alayhi wa sallam) said, “In the presence of three people, two should not hold secret counsel, to the exclusion of the third.”. In Abu Dawud, Abu Salih related: I asked Ibn Umar: “What if there are four people.”
He said, “There is no harm in that.”Malik reported in Al-Muwatta that Abdullah ibn Dinar related: Ibn Umar and I were together in Khalid ibn Uqbah’s house which was situated in the market place. A man came to consult Ibn Umar None besides me was present.
Ibn Umar called another man in and we became four and said to me and the man he had called: Move away a bit because I have heard the Messenger of Allah (sallallahu alayhi wa sallam) saying, “The two people should not hold secret counsel together excluding the third.”
