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 bin Dinar related: Ibn 'Umar and I were together in Khalid bin '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 (Peace be upon him) saying, "The two people should not hold secret counsel together excluding the third."

Selon Ibn Omar (das), le Messager de Dieu (bsdl) a dit: «Quand ils sont trois compagnons, que deux d"entre eux ne se concertent pas à voix basse sans y faire participer le troisième».

Hadith 1599 - Bab 281 (Prohibition of two Holding Secret Counsel to the Exclusion of Conversing together a Third)
Chapter 18 (The Book of the Prohibited actions)

Ibn Mas'ud (May Allah be pleased with him) said: The Messenger of Allah (Peace be upon him) said, "When three of you are together, two of you must not converse privately ignoring the third till the number increases, lest the third should be grieved."

Selon Ibn Mas"ùd (das), le Messager de Dieu (bsdl) a dit: «Quand vous êtes trois, que deux d"entre vous ne se concertent pas à voix basse sans la participation du troisième jusqu"à ce que vous vous mêliez aux gens car cela pourrait le chagriner».
