Muwatta Malik, Book 41, Hadith 8 (USC-MSA) ⓘ

Malik related to me from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud that Abdullah ibn Abbas said, "I heard Umar ibn al- Khattab say, 'Stoning is in the Book of Allah for those who commit adultery, men or women when they are muhsan and when there is clear proof of pregnancy or a confession.' "

حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ قَالَ سَمِعْتُ عُمَرَ بْنَ الْخَطَّابِ، يَقُولُ الرَّجْمُ فِي كِتَابِ اللَّهِ حَقٌّ عَلَى مَنْ زَنَى مِنَ الرِّجَالِ وَالنِّسَاءِ إِذَا أُحْصِنَ إِذَا قَامَتِ الْبَيِّنَةُ أَوْ كَانَ الْحَبَلُ أَوْ الاِعْتِرَافُ ‏.‏
