Al-Adab Al-Mufrad, Book 23, Hadith 1 (In-Book) ⓘ
Salim ibn 'Abdullah reported from his father that 'Umar used to say to his sons, "Separate in the morning and do not meet together in the same house. I fear that you might split up or that some evil may take place between you."
حَدَّثَنَا مَخْلَدُ بْنُ مَالِكٍ، قَالَ: حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَغْرَاءَ، قَالَ: حَدَّثَنَا الْفَضْلُ بْنُ مُبَشِّرٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللهِ، عَنْ أَبِيهِ، كَانَ عُمَرُ يَقُولُ لِبَنِيهِ: إِذَا أَصْبَحْتُمْ فَتَبَدَّدُوا، وَلاَ تَجْتَمِعُوا فِي دَارٍ وَاحِدَةٍ، فَإِنِّي أَخَافُ عَلَيْكُمْ أَنْ تَقَاطَعُوا، أَوْ يَكُونَ بَيْنَكُمْ شَرٌّ.
