It is narrated from Sayyiduna Safinah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) had himself cupped and said (to me): "Take this blood and bury it, hidden from the animals, the birds and the people." I went out of sight and drank the blood, then I mentioned it to him (peace and blessings be upon him), and he (peace and blessings be upon him) laughed. (These are the words of Ahmad bin Salih.)
