“This is about the case of four men who testified against an al-Muhsin (married man) due to fornication of whom two retracted their testimony and not the other two. Abu ‘Abd Allah (a.s.), has said, ‘If the four are Muslims who are not known as falsely testifying people, the testimony of all four is admissible, and penalty must be applied on the one against whom they have testified, however, they must testify only to what they have seen and have the knowledge thereof. The person in authority must accept their testimony unless they are known to be sinful people.’”
