salam, I am wondering if you could elaborate on a certain hadith in al Khisal: THE MIND OF A MAN BELONG TO THREE : Abu Abdullah(A.S) said: The mind of a man belongs to three; in his beard’s length; in the carving of his ring; and in his surname. I am guessing that the surname means something to do with genetics, and the beard implies having a beard is good for your mind. However, I am very confused regarding ring carvings. Could you inform me about the meaning of this hadith? Thank you very much, I appreciate it greatly.
