Sayyiduna Ali (may Allah be pleased with him) says that regarding anyone upon whom I have carried out any prescribed punishment, I do not feel any unease in my heart, except for (the punishment of) alcohol. If, after administering its punishment of eighty lashes, someone dies, then I pay his blood money, because the Prophet (peace and blessings be upon him) did not specify any fixed limit for it (whether forty lashes should be given or eighty).
