Jami` at-Tirmidhi, Volume 3, Book 15, Hadith 1435 (DarusSalam) ⓘ

Narrated 'Imran bin Husain: "A woman from Juhainah confessed before the Prophet that she had committed adultery, and she said: 'I am pregnant.' So the Prophet called for her guardian and said: 'Be good to her and if she gives birth to her child then tell me.' So he did so, and then he gave the order that her clothes be bound tightly around her. Then he ordered her to be stoned and she was stoned. Then he performed (funeral) Salat for her. So 'Umar bin Al-Khattab said to him: 'O Messenger of Allah! You stoned her then you prayed for her?!' He said: 'She has repented a repentance that, if distributed among seventy of the people of Al-Madinah, it would have sufficed them. Have you ever seen something more virtuous than her sacrificing herself for the saek of Allah?'"

حَدَّثَنَا الْحَسَنُ بْنُ عَلِيٍّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ أَبِي قِلاَبَةَ، عَنْ أَبِي الْمُهَلَّبِ، عَنْ عِمْرَانَ بْنِ حُصَيْنٍ، أَنَّ امْرَأَةً، مِنْ جُهَيْنَةَ اعْتَرَفَتْ عِنْدَ النَّبِيِّ صلى الله عليه وسلم بِالزِّنَا فَقَالَتْ إِنِّي حُبْلَى ‏.‏ فَدَعَا النَّبِيُّ صلى الله عليه وسلم وَلِيَّهَا فَقَالَ ‏"‏ أَحْسِنْ إِلَيْهَا فَإِذَا وَضَعَتْ حَمْلَهَا فَأَخْبِرْنِي ‏"‏ ‏.‏ فَفَعَلَ فَأَمَرَ بِهَا فَشُدَّتْ عَلَيْهَا ثِيَابُهَا ثُمَّ أَمَرَ بِرَجْمِهَا فَرُجِمَتْ ثُمَّ صَلَّى عَلَيْهَا فَقَالَ لَهُ عُمَرُ بْنُ الْخَطَّابِ يَا رَسُولَ اللَّهِ رَجَمْتَهَا ثُمَّ تُصَلِّي عَلَيْهَا ‏.‏ فَقَالَ ‏"‏ لَقَدْ تَابَتْ تَوْبَةً لَوْ قُسِمَتْ بَيْنَ سَبْعِينَ مِنْ أَهْلِ الْمَدِينَةِ لَوَسِعَتْهُمْ وَهَلْ وَجَدْتَ شَيْئًا أَفْضَلَ مِنْ أَنْ جَادَتْ بِنَفْسِهَا لِلَّهِ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
