عَنْ مَعْبَدِ بْنِ سِيرِينَ رَضِيَ اللَّهُ عَنْهُ عَنْ رَجُلٍ مِنَ الْأَنْصَارِ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَعَتَ مِنْ عِرْقِ النَّسَا أَنْ تُؤْخَذَ أَلْيَةُ كَبْشٍ عَرَبِيٍّ لَيْسَتْ بِصَغِيرَةٍ وَلَا عَظِيمَةٍ فَتُذَابَ ثُمَّ تُجَزَّأَ ثَلَاثَةَ أَجْزَاءٍ فَيُشْرَبَ كُلَّ يَوْمٍ عَلَى رِيقِ النَّفَسِ جُزْءًا
Sayyiduna Ma’bad bin Sirin narrates from a man of the Ansar, and that Ansari narrates from his father that the Noble Prophet (peace and blessings be upon him) prescribed the treatment for the disease of sciatica (irq al-nasa) as follows: An Arabian ram should be taken, which is neither very young nor very old. The meat from its hip should be taken and melted, that is, broth should be made from it, and it should be divided into three parts. Each day, one part should be drunk on an empty stomach.
