Narrated Tawus: Umar stood on the pulpit. He then mentioned the rest of the tradition to the same effect as mentioned before. He did not mention "that she should be killed". This version adds: "a male or a female slave". Umar then said: Allah is Most Great. Had I not heard it, we would have decided about it something else.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الزُّهْرِيُّ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ طَاوُسٍ، قَالَ قَامَ عُمَرُ رضى الله عنه عَلَى الْمِنْبَرِ فَذَكَرَ مَعْنَاهُ لَمْ يَذْكُرْ وَأَنْ تُقْتَلَ . زَادَ بِغُرَّةٍ عَبْدٍ أَوْ أَمَةٍ . قَالَ فَقَالَ عُمَرُ اللَّهُ أَكْبَرُ لَوْ لَمْ أَسْمَعْ بِهَذَا لَقَضَيْنَا بِغَيْرِ هَذَا .
