Question : It is only that it should be.
Answer : We proceed. No, that is a statement of fact. What is in the hadith is a statement of fact, not an address. That is to say, if you address someone and say to him, "O Black one," yes, that is fine if there is no harm, meaning if he does not get tired of it or become angry about it, then there is no harm. The Messenger (peace and blessings be upon him) used to call the man with long hands, saying, "Call him O one with two hands."
