Ahmad, Ibn Mājah and al-Tirmidhī.

‘Abd al-Rahmān ibn ‘Uthmān narrated:

“A physician mentioned a medicine in the presence of the Messenger of Allah—may Allah bless him and grant him peace—and mentioned that a frog was included in it. The Messenger of Allah—may Allah bless him and grant him peace—forbade killing frogs.”

“Every intoxicant is khamr, and all khamr is forbidden.”

Another version reads:

Likewise, in the two Sahīhs, ‘Ā’ishah narrated:
