Hadith 6225

(حديث مرفوع) حَدَّثَنَا نُوحٌ ، أَخْبَرَنَا عَبْدُ اللَّهِ ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ ، قَالَ : رَأَيْتُ ابْنَ عُمَرَ يُنَاجِي رَجُلًا ، فَدَخَلَ رَجُلٌ بَيْنَهُمَا ، فَضَرَبَ صَدْرَهُ ، وَقَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِذَا تَنَاجَى اثْنَانِ ، فَلَا يَدْخُلْ بَيْنَهُمَا الثَّالِثُ إِلَّا بِإِذْنِهِمَا " .
Saeed Maqbari (may Allah have mercy on him) says that once I saw that Sayyiduna Ibn Umar (may Allah be pleased with them both) was talking to someone, and a man came and sat between them. He (Ibn Umar) struck his hand on his chest and said: The Prophet (peace and blessings be upon him) said: When two people are talking secretly, do not sit with them without their permission.
