Does the Hadith about the Prophet (peace and blessings be upon him) passing by a boy skinning a sheep, and his (the Prophet's) hand going between the skin and the meat, then his praying without performing ablution, indicate the ritual purity of the blood of an animal whose meat is permissible to eat? What is the ruling on the blood of an animal whose meat is not permissible to eat, and does this include dogs and pigs? What is the meaning of "al-dahs" (دحس), and why did the Prophet do that?

The meaning of "فَدَحَسَ بها" (fadahas biha) is: he inserted his hand between the skin of the sheep and its inner membrane to skin it. "لم يتوضأ" (lam yatawaḍḍaʾ) means he did not wash his hand. The blood of an animal whose meat is permissible to eat, after its slaughtering, is pure, except for flowing (effused) blood, which is impure. What remains in the veins of the sheep after slaughtering or in its heart is pure, but what is in its abdomen or at the place of slaughter is impure. Pig's blood is impure according to the Quranic text, and the blood of an animal whose meat is not permissible to eat is also impure, because its slaughtering does not purify its skin or its meat. The reason the Prophet, peace and blessings be upon him, inserted his hand to skin the sheep was due to his noble character and his eagerness to help the young boy.
