A Thought on Eid-ul-Adha and Other Faiths

Assalamu alaikum, I've been pondering something. Since Eid-ul-Adha follows the sunnah of Prophet Ibrahim (peace be upon him), why don't our Jewish and Christian brothers and sisters observe it too? It's not solely from Prophet Muhammad's teachings, so I'm curious why the tradition of sacrifice in Dhul-Hijjah isn't shared among Abrahamic faiths.
