It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the cup of the Prophet (peace and blessings be upon him) cracked, so he (peace and blessings be upon him) joined the broken place with a silver wire. Asim says: I saw that cup and also drank from it. My father says: I saw that cup and drank from it.
