Given name Jabir ibn Abdullah. Title/Tribal affiliation al-Ansari. Jabir was a renound companion of the Prophet Muhammad and several of Muhammad's descendents, the Shi'a Imams.

Due to old age Jabir was unable to participate in the Battle of Karbala (10th October 680 CE) wherein the grandson of the Prophet, Hussein ibn Ali was martyred. However, he did establish the practice of marking arba'een.

It is narrated that Jabir was in the presence of the Muhammad when the Prophet told him: “O Jabir, you will have a long life, and although you will go blind, but you will meet the 5th in line of my descendants whose name will be my name, who will walk like me and who will be the 5th Imam (see Shia Imams of the time. When you will meet him, give my salaams to him”.

Jabir had a long life and became blind in his old age. But he devoutly waited for the time when he would meet the 5th Imam. Each morning he would come out from his house, sit by the roadside and wait for the sound of the footsteps to recognize the 5th Imam. One such day while he was waiting in the street of Medina, he heard someone walking towards him, the sound of footsteps reminded him of the way the Prophet used to walk. Jabir stood up, stopped the man and asked his name. He replied, “Muhammad”, Jabir asked, whose son? he replied “Ali ibn Hussein”. Jabir immediately recognized the man he was talking to was the 5th Imam. He kissed his hands and conveyed the message from the Prophet.
