Does Allah command us to view the sacrifice of animal on Eid-Ul-Adha?

On the occasion of Eid-Ul-Adha, has Allah commanded the Muslims to view the sacrifice of the animal on that day? Let's say I have an animal that will be sacrificed on Eid-Ul-Adha and I am not comfortable slaughtering the animal even though I am fit and fine, then does Allah command me to view the slaughtering of the animal? If I am fit and fine, then am I obliged to slaughter the animal myself? Please clarify !!!
