Does anyone know the reference for this hadith

I've heard this hadith being quoted as evidence for the Sufi hadra but cant find the reference even though its said to be in sahih Muslim "An army came from Ethiopia beating drums on the day of the feast in the mosque. The Prophet (صلى الله عليه وسلم) invited me and I put my palms on his shoulders and watched them play". Can anyone find the reference for this please.
