When there are four people

'Abdullah reported that the Prophet ﷺ said, "When there are three people, two should not converse together to the exclusion of the third for that would grieve him."

حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ قَالَ: حَدَّثَنِي أَبِي، قَالَ: حَدَّثَنَا الأَعْمَشُ قَالَ: حَدَّثَنِي شَقِيقٌ، عَنْ عَبْدِ اللهِ قَالَ: قَالَ النَّبِيُّ ﷺ: إِذَا كُنْتُمْ ثَلاَثَةً فَلاَ يَتَنَاجَى اثْنَانِ دُونَ الثَّالِثِ، فَإِنَّهُ يُحْزِنُهُ ذَلِكَ.

Ibn 'Umar reported something similar from the Prophet, may Allah bless him and grant him peace. He stated, "We said, 'If there are four?' He said, 'Then it will not harm him.'"

وَحَدَّثَنِي أَبُو صَالِحٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ ﷺ مِثْلَهُ، قُلْنَا: فَإِنْ كَانُوا أَرْبَعَةً؟ قَالَ: لا يَضُرُّهُ.

'Abdullah reported that the Prophet ﷺ said, "Two should not converse to the exclusion of another until they are mixing with people since that would distress him."

حَدَّثَنَا عُثْمَانُ، قَالَ: حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنْ أَبِي وَائِلٍ، عَنْ عَبْدِ اللهِ، عَنِ النَّبِيِّ ﷺ قَالَ: لاَ يَتَنَاجَى اثْنَانِ دُونَ الْآخَرِ حَتَّى يَخْتَلِطُوا بِالنَّاسِ، مِنْ أَجْلِ أَنَّ ذَلِكَ يُحْزِنُهُ.
