Musnad Ahmad

Hazrat Rafi’ Ta’i, who was a companion of Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) in the Battle of Dhat al-Salasil, says: I asked Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) about the statements made regarding the allegiance of the Ansar. He then narrated those statements which the Ansar had said, or which he himself had said, or which Sayyiduna Umar Farooq (may Allah be pleased with him) had said to the Ansar. He also reminded them that, by the order of the Prophet (peace and blessings be upon him), during his final illness, those people continued to pray under my leadership. Upon this, all the Ansar pledged allegiance to me and I accepted it on their behalf. Later, I feared that this might become a cause for some trial, and indeed, after that, the trial of apostasy occurred.
