Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الْأَنْصَارِيُّ حَدَّثَنَا هِشَامُ بْنُ حَسَّانَ عَنْ أَنَسِ بْنِ سِيرِينَ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَصِفُ مِنْ عِرْقِ النَّسَا أَلْيَةَ كَبْشٍ عَرَبِيٍّ أَسْوَدَ لَيْسَ بِالْعَظِيمِ وَلَا بِالصَّغِيرِ يُجَزَّأُ ثَلَاثَةَ أَجْزَاءٍ فَيُذَابُ فَيُشْرَبُ كُلَّ يَوْمٍ جُزْءٌ.
English Translation
Muhammad ibn Abdullah al-Ansari told us: Hisham ibn Hassan told us, from Anas ibn Sirin, from Anas ibn Malik, that the Prophet, peace and blessings be upon him, used to describe, for sciatica, the tail-fat of a black Arabian ram, neither too large nor too small, divided into three portions, melted down and drunk one portion each day.
