Narrator:Abdullāh ibn ‘Umar
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ "
إِذَا كَانَ ثَلاَثَةٌ فَلاَ يَتَنَاجَى اثْنَانِ دُونَ وَاحِدٍ "
Ibn Umar reported Allah's Messenger (ﷺ) as saying:
When there are three (persons), two should not converse secretly between themselves to the exclusion of the (third) one.
