A Jew, a Christian and a slave giving testimony

Al-Zuhri and Qatadah said: If a person of the Book, a slave and a child are witnesses, and then the person of the Book becomes a Muslim, the slave is freed and the child grows up, it is valid for them to give their testimony. However, if their testimony was rejected while they were in their former state, then it is not permissible.

Al-Zuhri (may Allah have mercy on him) said: If a slave gives testimony while in slavery and his testimony is rejected, and then he is freed, his testimony (in the same matter in which it was previously rejected) is not valid.

Al-Hasan said: If a slave and a dhimmi give testimony and their testimony is rejected, and then the slave is freed and the dhimmi becomes a Muslim, their testimony is valid.

Ibrahim (may Allah have mercy on him) said: If a slave gives testimony and his testimony is rejected, and then he is freed, that testimony of his is not accepted.

Al-Hakam (may Allah have mercy on him) said: His testimony is valid.

Abu Salamah said: If a slave gives testimony and his testimony is rejected, and then he is freed, his testimony is not accepted.

Shurayh (may Allah have mercy on him) said: If a slave gives testimony and his testimony is rejected, and then he is freed, his testimony is not accepted.

Sayyiduna Umar (may Allah be pleased with him) said concerning the testimony of a Jew, a Christian and a slave: When they witnessed something and were not able to deliver that testimony until the slave was freed and the Jew and the Christian became Muslims, their testimony is valid.
