ʿUmar said: Allah, may He be exalted, sent Muhammad ﷺ and sent down the Book to him. Among that which was revealed to him was the verse of stoning. We recited it and understood it. But I fear that with the passage of time, some people will say: We do not find the verse of stoning in the Book of Allah, and as a result an obligation that Allah revealed will be forsaken. Stoning is the due punishment in the Book of Allah for those who commit zina, both men and women, if they have been married and if proof is established, or there is a pregnancy or a confession. (Using translation from Aḥmad 276)   

عُمَرُ إِنَّ اللَّهَ تَعَالَى بَعَثَ مُحَمَّدًا ﷺ بِالْحَقِّ وَأَنْزَلَ عَلَيْهِ الْكِتَابَ وَكَانَ فِيمَا أَنْزَلَ آيَةُ الرَّجْمِ فَقَرَأْنَاهَا وَوَعَيْنَاهَا وَعَقَلْنَاهَا وَرَجَمَ رَسُولُ اللَّهِ ﷺ وَرَجَمْنَا بَعْدَهُ فَأَخْشَى إِنْ طَالَ بِالنَّاسِ زَمَانٌ أَنْ يَقُولَ الْقَائِلُ لَا نَجِدُ حَدَّ آيَةِ الرَّجْمِ فِي كِتَابِ اللَّهِ وَالرَّجْمُ فِي كِتَابِ اللَّهِ حَقٌّ عَلَى مَنْ زَنَى مِنَ الرِّجَالِ وَالنِّسَاءِ إِذَا أُحْصِنَ إِذَا قَامَتْ عَلَيْهِ الْبَيِّنَةُ أَوْ كَانَ الْحَبَلُ أَوِ الِاعْتِرَافُ
