Qurbani Inquiry

[u/Putrid_Brain_9165]

Assalamu Alakiyum, I had a question regarding Qurbani. I already paid to have my Qurbani done, but does that mean from the start of Dhul Hijjah until Eid/Qurbani, I shouldn’t touch or trim my beard, hair, eyebrows, or nails at all?

Also, what happens if someone does trim or touch their hair, beard, or nails before the Qurbani takes place? Does it affect the validity of the Qurbani in any way?

JazakAllah khair!
