حَدَّثَنِي مَالِكٌ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، عَنْ أَبِي وَاقِدٍ اللَّيْثِيِّ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، أَتَاهُ رَجُلٌ وَهُوَ بِالشَّامِ فَذَكَرَ لَهُ أَنَّهُ وَجَدَ مَعَ امْرَأَتِهِ رَجُلاً فَبَعَثَ عُمَرُ بْنُ الْخَطَّابِ أَبَا وَاقِدٍ اللَّيْثِيَّ إِلَى امْرَأَتِهِ يَسْأَلُهَا عَنْ ذَلِكَ فَأَتَاهَا وَعِنْدَهَا نِسْوَةٌ حَوْلَهَا فَذَكَرَ لَهَا الَّذِي قَالَ زَوْجُهَا لِعُمَرَ بْنِ الْخَطَّابِ وَأَخْبَرَهَا أَنَّهَا لاَ تُؤْخَذُ بِقَوْلِهِ وَجَعَلَ يُلَقِّنُهَا أَشْبَاهَ ذَلِكَ لِتَنْزِعَ فَأَبَتْ أَنْ تَنْزِعَ وَتَمَّتْ عَلَى الاِعْتِرَافِ فَأَمَرَ بِهَا عُمَرُ فَرُجِمَتْ ‏.‏

Malik related to me from Yahya ibn Said from Sulayman ibn Yasarfrom Abu Waqid al-Laythi that a man came to Umar ibn al-Khattab whilehe was in ash-Sham . He mentioned to him that he had found a man withhis wife Umar sent Abu Waqid al-Laythi to the wife to question herabout that. He came to her while there were women around her andmentioned to her what her husband had mentioned to Umar ibn al-Khattab, and informed her that she would not be punished on his wordand began to suggest to her by that, that she should retract. Sherefused to retract and held firm to confession. Umar gave the orderand she was stoned. Translation Not Available
