Ibrahim bin Muhammad al-Ribati related in Rajab of the year 266 AH that it was read out to Abu Ubayd.
(b) Sayyidah Aishah (may Allah be pleased with her) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "The testimony of a treacherous man and a treacherous woman, of one who harbours rancour against his brother, of one who makes accusations regarding clientage and kinship, and of a servant in favour of his master shall not be accepted."
This is the wording of Ali's narration; in al-Ribati's narration it is: "nor one under suspicion, nor one suspected on account of kinship." The first is more correct, and this Yazid is da'if (weak).
