'Abdullah reported that the Prophet, may Allah bless him and grant
him peace, said, "When there are three people, two should not converse
together to the exclusion of the third for that would grieve him."
حَدَّثَنَا إِسْمَاعِيلُ قَالَ: حَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللهِ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ: إِذَا كَانُوا ثَلاَثَةً، فَلاَ يَتَنَاجَى اثْنَانِ دُونَ الثَّالِثِ.
'Abdullah reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "When there are three people, two should
not converse together to the exclusion of the third."
وَحَدَّثَنِي أَبُو صَالِحٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم مِثْلَهُ، قُلْنَا: فَإِنْ كَانُوا أَرْبَعَةً؟ قَالَ: لا يَضُرُّهُ.
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.'"
Ibn 'Abbas said, "Whoever listens to people's conversations when
they do not want him to do so will have molten lead poured into his ears.
Anyone who lies about a dram will be obliged to string a barley bead."
