Malik related to me from Nafi that Abdullah ibn Umar said, "The Jews came to the Messenger of Allah ﷺ and mentioned to him that a man and woman from among them had committed adultery. The Messenger of Allah ﷺ asked them, 'What do you find in the Torah about stoning?' They said, 'We make their wrong action known and flog them.' Abdullah ibn Salam said, 'You have lied! It has stoning for it, so bring the Torah.' They spread it out and one of them placed his hand over the ayat of stoning. Then he read what was before it and what was after it. Abdullah ibn Salam told him to lift his hand. He lifted his hand and there was the ayat of stoning. They said, 'He has spoken the truth, Muhammad. The ayat of stoning is in it.' So the Messenger of Allah ﷺ gave the order and they were stoned . "
Abdullah ibn Umar added, "I saw the man leaning over the woman to protect her from the stones."
Malik commented, "By leaning he meant throwing himself over her so that the stones fell on him."

حَدَّثَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ جَاءَتِ الْيَهُودُ إِلَى رَسُولِ اللَّهِ ﷺ فَذَكَرُوا لَهُ أَنَّ رَجُلاً مِنْهُمْ وَامْرَأَةً زَنَيَا فَقَالَ لَهُمْ رَسُولُ اللَّهِ ﷺ " مَا تَجِدُونَ فِي التَّوْرَاةِ فِي شَأْنِ الرَّجْمِ " . فَقَالُوا نَفْضَحُهُمْ وَيُجْلَدُونَ . فَقَالَ عَبْدُ اللَّهِ بْنُ سَلاَمٍ كَذَبْتُمْ إِنَّ فِيهَا الرَّجْمَ . فَأَتَوْا بِالتَّوْرَاةِ فَنَشَرُوهَا فَوَضَعَ أَحَدُهُمْ يَدَهُ عَلَى آيَةِ الرَّجْمِ ثُمَّ قَرَأَ مَا قَبْلَهَا وَمَا بَعْدَهَا فَقَالَ لَهُ عَبْدُ اللَّهِ بْنُ سَلاَمٍ ارْفَعْ يَدَكَ فَرَفَعَ يَدَهُ فَإِذَا فِيهَا آيَةُ الرَّجْمِ فَقَالُوا صَدَقَ يَا مُحَمَّدُ فِيهَا آيَةُ الرَّجْمِ . فَأَمَرَ بِهِمَا رَسُولُ اللَّهِ ﷺ فَرُجِمَا . فَقَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ فَرَأَيْتُ الرَّجُلَ يَحْنِي عَلَى الْمَرْأَةِ يَقِيهَا الْحِجَارَةَ .
