Hazrat Namila Fazari says that once I was present in the service of Hazrat Ibn Umar (may Allah be pleased with him) when someone asked him about the "Siyah" (a particular kind of animal). He recited this verse before him: "Say: I do not find in what has been revealed to me anything forbidden..." to the end. Then an elder said that I heard Hazrat Abu Huraira (may Allah be pleased with him) say that once this was mentioned before the Holy Prophet (peace and blessings be upon him), so the Holy Prophet (peace and blessings be upon him) said that it is among the filthy things. Upon this, Hazrat Ibn Umar (may Allah be pleased with him) said that if indeed the Holy Prophet (peace and blessings be upon him) said this, then it is just as the Holy Prophet (peace and blessings be upon him) said.
