if muhammad ibn ali did it then he is not a volunteer in doing it and he forbade it and he was cupped and gave the blood to a man to bury and he said beware that a dog searches for it!
وإن فعله محمد بن علي فليس بمتبرع من الفعل وقد نهى عنه ، وأنه احتجم فأعطى الدم رجلا ليدفنه وقال احذر أن يبحث عليه الكلب! .
