لَّوْلَا جَآءُو عَلَيْهِ بِأَرْبَعَةِ شُهَدَآءَ ۚ فَإِذْ لَمْ يَأْتُوا۟ بِٱلشُّهَدَآءِ فَأُو۟لَٰٓئِكَ عِندَ ٱللَّهِ هُمُ ٱلْكَٰذِبُونَ
Commentary:
As stated above, not only does Islam take a very serious view of the crimes against chastity and punishes them severely, it is also very sensitive about the good reputation of Muslim men and women and takes very effective steps to safeguard it. Islam regards it as highly reprehensible and even criminal to spread false accusations against them. According to this verse, he who accuses a Muslim man or woman of adultery and does not produce four witnesses to prove his allegation shall be held to be a liar and treated as such by the Islamic Law even if he can produce one, two or even three persons as eye-witnesses to the act. The fact of one person seeing another person committing this immoral act does not entitle him to go about spreading the evil report.
