صحیح مسلم · Hadith 4434

Imran b. Husain reported that a woman from Juhaina came to Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and she had become pregnant because of adultery. She said: Allah's Apostle, I have done something for which (prescribed punishment) must be imposed upon me, so impose that. Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) called her master and said: Treat her well, and when she delivers bring her to me. He did accordingly. Then Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) pronounced judgment about her and her clothes were tied around her and then he commanded and she was stoned to death. He then prayed over her (dead body). Thereupon Umar said to him: Allah's Apostle, you offer prayer for her, whereas she had committed adultery! Thereupon he said: She has made such a repentance that if it were to be divided among seventy men of Medina, it would be enough. Have you found any repentance better than this that she sacr ficed her life for Allah, the Majestic?
