Hadith 14:299
Abu Bakr narrated to us, he said: Makhlad ibn Yazid—and he was trustworthy—narrated to us, from Ibn Jurayj, from ‘Ata’: That he was asked about a man whose liver was aching, and it was prescribed for him that he should have his liver lanced and drink from its blood. He said: "There is no harm in it; it is a necessity." Ibn Jurayj said: I said to him: "Is blood not forbidden?" He said: "That is out of necessity."
حدثنا أبو بكر قال حدثنا مخلد بن يزيد وكان ثقة عن بن جريج عن عطاء أنه سئل عن رجل وجع كبده فنعت له أن يشرط على كبده وأن يشرب من دمه فقال لا بأس هي ضرورة قال بن جريج قلت له أليس الدم حراما قال ذلك من ضرورة
