وَ رَوَى مُحَمَّدُ بْنُ أَبِي عُمَيْرٍ عَنْ إِسْحَاقَ بْنِ هِلاَلٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ "أَنَّ أَمِيرَ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ قَالَ: "أَ لاَ أُخْبِرُكُمْ بِأَكْبَرِ اَلزِّنَا" قَالُوا بَلَى قَالَ "هِيَ اِمْرَأَةٌ تُوطِئُ فِرَاشَ زَوْجِهَا فَتَأْتِي بِوَلَدٍ مِنْ غَيْرِهِ فَتُلْزِمُهُ زَوْجَهَا فَتِلْكَ اَلَّتِي لاَ يُكَلِّمُهَا اَللَّهُ وَ لاَ يَنْظُرُ إِلَيْهَا يَوْمَ اَلْقِيَامَةِ وَ لاَ يُزَكِّيهَا وَ لَهَا عَذَابٌ أَلِيمٌ" ".
Muhammad ibn Abi Umayr narrated from Ishaq ibn Hilal, from Abu Abdillah (a.s), who said: "Indeed, Commander of the Faithful (a.s) said: 'Shall I not inform you of the gravest form of adultery?' They said: 'Yes.' Imam (a.s) said: 'It is when a woman brings another man onto her husband's bed and bears a child from him, then attributes that child to her husband. That woman is the one whom Allah (swt) will neither speak to nor look at on the Day of Judgment, nor will He (swt) purify her, and for her is a painful punishment.'"
