Arabic (Original)
حَدَّثَنَا أَحْمَدُ بْنُ الْحَجَّاجِ حَدَّثَنَا عَبْدُ اللَّهِ أَخْبَرَنَا مُصْعَبُ بْنُ ثَابِتٍ حَدَّثَنِي أَبُو حَازِمٍ قَالَ سَمِعْتُ سَهْلَ بْنَ سَعْدٍ السَّاعِدِيَّ يُحَدِّثُ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ إِنَّ الْمُؤْمِنَ مِنْ أَهْلِ الْإِيمَانِ بِمَنْزِلَةِ الرَّأْسِ مِنْ الْجَسَدِ يَأْلَمُ الْمُؤْمِنُ لِأَهْلِ الْإِيمَانِ كَمَا يَأْلَمُ الْجَسَدُ لِمَا فِي الرَّأْسِ.
English Translation
Ahmad ibn al-Hajjaj narrated to us: 'Abdullah narrated to us: Mus'ab ibn Thabit informed us: Abu Hazim narrated to me, he said: I heard Sahl ibn Sa'd al-Sa'idi narrating from the Prophet, peace and blessings be upon him, who said: "The believer, among the people of faith, is like the head to the body -- the believer feels pain for the people of faith just as the body feels pain for what afflicts the head."
