Sahih Muslim 1689
Sahih Muslim · Book 29: The Book of Legal Punishments · Cutting off the hand of a thief from the nobility and others; the prohibition of interceding with regard to Hudud punishments
Jaibir reported that a woman from the tribe of Makhzum committed theft. She was brought to Allah's Apostle (ﷺ) and she sought refuge (intercession) from Umm Salama, the wife of Allah's Apostle (ﷺ). Thereupon Allah's Apostle (ﷺ) said:
وَحَدَّثَنِي سَلَمَةُ بْنُ شَبِيبٍ ، حَدَّثَنَا الْحَسَنُ بْنُ أَعْيَنَ ، حَدَّثَنَا مَعْقِلٌ ، عَنْ أَبِي الزُّبَيْرِ ، عَنْ جَابِرٍ ، أَنَّ امْرَأَةً، مِنْ بَنِي مَخْزُومٍ سَرَقَتْ فَأُتِيَ بِهَا النَّبِيُّ صلى الله عليه وسلم فَعَاذَتْ بِأُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ صلى الله عليه وسلم فَقَالَ النَّبِيُّ صلى الله عليه وسلم " وَاللَّهِ لَوْ كَانَتْ فَاطِمَةُ لَقَطَعْتُ يَدَهَا " . فَقُطِعَتْ .
By Allah, even if she were Fatima, I would have her hand cut off. And thus her hand was cut off.
