١ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنِ الْمُفَضَّلِ بْنِ عُمَرَ قَالَ قَالَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) إِنَّمَا الْمُؤْمِنُونَ إِخْوَةٌ بَنُو أَبٍ وَأُمٍّ وَإِذَا ضَرَبَ عَلَى رَجُلٍ مِنْهُمْ عِرْقٌ سَهِرَ لَهُ الآخَرُونَ.
1. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from ‘Uthman ibn ‘Isa from al-Mufaddal ibn ‘Umar who has said the following: “Abu ‘Abd Allah  has said, ‘The believers are but brothers, sons of one father and mother (in the original creation). If one of them may have an distressed vein, others will remain awake all night because of his pain.’”
