Ata bin Abi Rabah narrates that he heard Abdullah bin Abbas (may Allah be pleased with them both) saying that during the blessed time of the Prophet Muhammad (peace be upon him), a man was wounded, then he had a wet dream, so he was told to perform ghusl (ritual bath). He performed ghusl and then passed away. When this was reported to the Prophet Muhammad (peace be upon him), he said: "They have killed him. May Allah destroy them. Is the cure for ignorance not to ask?" The narrator named Ata states that we learned that when the Prophet Muhammad (peace be upon him) was asked about this, he said: "If that man had washed his body and left the part of his head where the wound was, it would have been correct."
