A man came to Abdullah bin Mas'ud (may Allah be pleased with him) and said: "My brother is ill; he has pain in his stomach, and he has been advised to drink wine. Shall I give it to him to drink?" Abdullah (may Allah be pleased with him) said: "Subhan Allah (Glory be to Allah)! Allah has not placed healing in anything filthy. Healing lies only in two things: honey is a healing for people, and the Qur'an is a healing for what is in the breasts."
