Sahih al-Bukhari — Asking Permission — Hadith No: 6290
حَدَّثَنَا عُثْمَانُ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ النَّبِيُّ صلى الله عليه وسلم {إِذَا كُنْتُمْ ثَلاَثَةً فَلاَ يَتَنَاجَى رَجُلاَنِ دُونَ الآخَرِ، حَتَّى تَخْتَلِطُوا بِالنَّاسِ، أَجْلَ أَنْ يُحْزِنَهُ}.
