Chapter on Whose Testimony Must Be Rejected and Whose Testimony Must Be Accepted

And it was narrated by Isma'il ibn Muslim, from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, from his father Imam Muhammad ibn Ali Al-Baqir عليه السلام, from his forefathers, from Imam Ali ibn Abi Talib عليه السلام, who said: "The testimony of children, if they testified while they were young, is valid when they grow older as long as they have not forgotten it. Likewise, the testimony of Jews and Christians, if they embrace Islam, is valid. Also, the testimony of a slave, if he was made to testify and then was freed, is valid as long as the judge did not reject it before his emancipation." And Imam عليه السلام said: "If the slave was freed specifically for the purpose of testimony, his testimony is not valid."
