Arabic (Original)
حَدَّثَنَا إِسْحَاقُ بْنُ يُوسُفَ حَدَّثَنَا الْأَعْمَشُ عَنْ أَبِي صَالِحٍ عَنِ ابْنِ عُمَرَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا كُنْتُمْ ثَلَاثَةً فَلَا يَتَنَاجَيَنَّ اثْنَانِ دُونَ صَاحِبِهِمَا.
English Translation
Ishaq ibn Yusuf told us; al-A'mash told us, from Abu Salih, from Ibn Umar, who said: The Messenger of Allah, peace and blessings be upon him, said: "When you are three, then two of you should not converse privately without the third among them."
