Abraham
According to a midrash in the Talmud, when Abraham was young, his father Terah told him to take care of his store selling idols but instead Abraham destroyed them except the biggest one and told Terah that it had destroyed the rest and Terah told him that idols are mindless statues and not deities so they couldn’t have done that. Then Abraham asked Terah why he worshipped them so Terah took him to King Nimrod who tried to kill him by burning him in a furnace but a miracle saved Abraham. So Nimrod asked Abraham’s brother Haran what he believed and Haran said he believed in the deity of Abraham because He would save him with a miracle. Then Nimrod threw Haran to the furnace and he died and Nimrod sent away Terah and his family. And then the Almighty told Abraham to go to Canaan.
