It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: The Messenger of Allah (peace and blessings be upon him) had only one woman of the women of Banu Qurayzah killed. By Allah! She was sitting with me, laughing until she was rolling about, while the Messenger of Allah (peace and blessings be upon him) was having their men killed with swords. Just then a caller called out her name: "Where is so-and-so?" She said: "By Allah! Here I am." I said (in astonishment): "Woe to you! What is the matter with you?" She said: "By Allah! I am going to be killed." I asked: "Why?" She said: "Because of a matter (a crime) that I committed." Then she was taken away and her neck was struck. I do not forget my amazement at the contentment of her soul and how much she smiled, despite knowing that she would be killed. This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.
