relatives
6ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) لا تَقْطَعْ رَحِمَكَ وَإِنْ قَطَعَتْكَ.
6. Ali ibn Ibrahim has narrated from his father from al-Nawfali from al-Sakuni from Abu ‘Abdillah (a.s.) who has said the following: “The Messenger of Allah has said, ‘Do not fail to maintain good relations with relatives, even if they fail to maintain good relations with you.’”
