It was narrated that Ibn 'Umar said:
"The Messenger of Allahﷺ forbade two to converse (privately) to the exclusion of a third."
حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنِ ابْنِ عُمَرَ، قَالَ نَهَى رَسُولُ اللَّهِ ـ ﷺ ـ أَنْ يَتَنَاجَى اثْنَانِ دُونَ الثَّالِثِ .
