'Abdullah b. 'Abbas reported that 'Umar b. Khattab sat on the pulpit of Messenger of Allah ﷺ and said: Verily Allah sent Muhammad ﷺ with truth and He sent down the Book upon him, and the verse of stoning was included in what was sent down to him. We recited it, retained it in our memory and understood it. Messenger of Allah ﷺ awarded the punishment of stoning to death (to the married adulterer and adulteress) and, after him, we also awarded the punishment of stoning, I am afraid that with the lapse of time, the people (may forget it) and may say: We do not find the punishment of stoning in the Book of Allah, and thus go astray by abandoning this duty prescribed by Allah. Stoning is a duty laid down in Allah's Book for married men and women who commit adultery when proof is established, or it there is pregnancy, or a confession.

حَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ بْنُ يَحْيَى، قَالاَ حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي عُبَيْدُ اللَّهِ بْنُ عَبْدِ اللَّهِ بْنِ عُتْبَةَ، أَنَّهُ سَمِعَ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، يَقُولُ قَالَ عُمَرُ بْنُ الْخَطَّابِ وَهُوَ جَالِسٌ عَلَى مِنْبَرِ رَسُولِ اللَّهِ ﷺ إِنَّ اللَّهَ قَدْ بَعَثَ مُحَمَّدًا ﷺ بِالْحَقِّ وَأَنْزَلَ عَلَيْهِ الْكِتَابَ فَكَانَ مِمَّا أُنْزِلَ عَلَيْهِ آيَةُ الرَّجْمِ قَرَأْنَاهَا وَوَعَيْنَاهَا وَعَقَلْنَاهَا فَرَجَمَ رَسُولُ اللَّهِ ﷺ وَرَجَمْنَا بَعْدَهُ فَأَخْشَى إِنْ طَالَ بِالنَّاسِ زَمَانٌ أَنْ يَقُولَ قَائِلٌ مَا نَجِدُ الرَّجْمَ فِي كِتَابِ اللَّهِ فَيَضِلُّوا بِتَرْكِ فَرِيضَةٍ أَنْزَلَهَا اللَّهُ وَإِنَّ الرَّجْمَ فِي كِتَابِ اللَّهِ حَقٌّ عَلَى مَنْ زَنَى إِذَا أَحْصَنَ مِنَ الرِّجَالِ وَالنِّسَاءِ إِذَا قَامَتِ الْبَيِّنَةُ أَوْ كَانَ الْحَبَلُ أَوْ الاِعْتِرَافُ .
