the Prophet (ﷺ) said "When three persons are together, then no two of them should hold secret counsel excluding the third person."

The Prophet (ﷺ) said, "When you are three persons sitting together, then no two of you should hold secret counsel excluding the third person until you are with some other people too, for that would grieve him."

If you are three, two amongst you should not converse secretly between yourselves to the exclusion of the other (third one), unti some other people join him (and dispel his loneliness), for it may hurt his feelings.

'Abdullah reported that the Prophet, (ﷺ), said, "Two should not converse to the exclusion of another until they are mixing with people since that would distress him."
