78. hadíth
وَ فِي رِوَايَةِ اَلسَّكُونِيِّ أَنَّهُ رُفِعَ إِلَى عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ: "رَجُلٌ وَقَعَ عَلَى اِمْرَأَةِ أَبِيهِ فَرَجَمَهُ وَ كَانَ غَيْرَ مُحْصَنٍ".
In the narration of Al-Sakuni, it was reported to Imam Ali ibn Abi Talib (a.s) that a man had committed fornication with his father's wife, so Imam (a.s) ordered him to be stoned, even though he was not married (non-muhṣan).
