Sunan At-Tirmidhi

Simak narrated that he heard 'Alqamah bin Wa'il narrate from his father, that he witnessed the Prophet (s.a.w) being asked by Suwaid bin Tariq -or Tariq bin Suwaid- about Khamr, and he forbade it. So he said:""We use it as a treatment."" So the Messenger of Allah (S.A.W) said: ""It is certainly not a treatment, rather, it is a disease."" Another chain reports a similar narration
