It is normal to remember Prophet Abraham with Eid Al-Adha. He is the one who started his historical trip to worship God. He fought for that goal, and then left it to his sons and prophets afterwards. Prophets kept the heritage, and transferred it with heavenly additions. When the period of the prophets ended, heaven left its message in the hands of people, for which they have done a lot. Some used it for gaining profit, some used it for convincing people of superstitions and some used it for war against others.
