Jabir ibn Abdullah was a close companion of Prophet Muhammad. The Prophet had said to him, “O’ Jabir, you will have a lengthy life and will meet someone from my progeny from the children of (Imam) Hossein whose name will be the same as my name, Muhammad.” The Prophet had said that he would be called Baqir, “the one who splits open the doors of knowledge”. The Prophet asked Jabir to pass his greetings to him upon their meeting. After many years, Jabir met Imam Baqir in Medina when the Imam was young. The Imam’s face reminded Jabir of the Prophet’s face. Jabir passed the Prophet’s greeting to the Imam and said, “You are Baqir, the one who will split open knowledge.”
