Narrator:Anas ibn Mālik
وَعَنْ أَنَسِ بْنِ مَالِكٍ - رضى الله عنه - قَالَ: { أَوَّلَ لِعَانٍ كَانَ فِي اَلْإِسْلَامِ أَنَّ شَرِيكَ بْنُ سَمْحَاءَ قَذَفَهُ هِلَالُ بْنُ أُمَيَّةَ بِاِمْرَأَتِهِ, فَقَالَ لَهُ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -
"اَلْبَيِّنَةَ وَإِلَّا فَحَدٌّ فِي ظَهْرِكَ "
Anas bin Malik (RAA) narrated, "The first Li'an that took place in Islam was when Hilal bin Umaiyah accused his wife of having committed adultery with Shuraik bin Sahma.' Thereupon the Messenger of Allah (ﷺ) said to him, "Either you produce evidence (for your claim) or you will receive punishment on your back (i.e. flogged for your accusation of it is false." (refer to hadith no.1138). Related by Abu Ya'la with a trustworthy chain of narrators.
