testimony
in Edition Clear Qur'an by Talal Itani / An-Noor (The Light)

24:4Those who accuse chaste women, then cannot bring four witnesses, whip them eighty lashes, and do not ever accept their testimony. For these are the immoral.

24:6As for those who accuse their own spouses, but have no witnesses except themselves, the testimony of one of them is equivalent to four testimonies, if he swears by God that he is truthful.
