And those who accuse their wives [of adultery] and have no witnesses except themselves - then the witness of one of them1 [shall be] four testimonies [swearing] by Allāh that indeed, he is of the truthful.
And those men who accuse their wives but do not have witnesses to testify to the authenticity of what they have accused them of besides themselves, one amongst them will testify by Allah four times: that he is truthful in the accusation of adultery he has made against his wife.
