Al-Adab Al-Mufrad, Book 12, Hadith 6 (In-Book) ⓘ
Anas reported that a Jewish woman brought the Prophet, may Allah bless him and grant him peace, poisoned sheep. He ate from it and she was brought. It was asked, "Should we not kill her?" "No," he replied.
حَدَّثَنَا عَبْدُ اللهِ بْنُ عَبْدِ الْوَهَّابِ، قَالَ: حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، قَالَ: حَدَّثَنَا شُعْبَةُ، عَنْ هِشَامِ بْنِ زَيْدٍ، عَنْ أَنَسٍ، أَنَّ يَهُودِيَّةً أَتَتِ النَّبِيَّ صلى الله عليه وسلم بِشَاةٍ مَسْمُومَةٍ، فَأَكَلَ مِنْهَا، فَجِيءَ بِهَا، فَقِيلَ: أَلاَ نَقْتُلُهَا؟ قَالَ: لاَ، قَالَ: فَمَا زِلْتُ أَعْرِفُهَا فِي لَهَوَاتِ رَسُولِ اللهِ صلى الله عليه وسلم.
