brotherhood
5ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ يَعْقُوبَ بْنِ شُعَيْبٍ قَالَ سَمِعْتُ أَبَا عَبْدِ الله (عَلَيهِ السَّلام) يَقُولُ مَنْ زَارَ أَخَاهُ فِي جَانِبِ الْمِصْرِ ابْتِغَاءَ وَجْهِ الله فَهُوَ زَوْرُهُ وَحَقٌّ عَلَى الله أَنْ يُكْرِمَ زَوْرَهُ.
5. A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from Sayf ibn ‘Amirah from Ya’qub ibn Shu’ayb who has said the following: “I heard Abu ‘Abdillah (a.s.) saying, ‘Whoever visits his brother (in belief) in a side of the city just to please Allah, has visited Him, and it becomes a responsibility for Allah to honor His visitor.’”
