أَخْبَرَنَا الْحَكَمُ بْنُ الْمُبَارَكِ ، حَدَّثَنَا مَالِكُ بْنُ أَنَسٍ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ : أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَدْرَكَ عُمَرَ بْنَ الْخَطَّابِ وَهُوَ يَسِيرُ فِي رَكْبٍ، وَهُوَ يَحْلِفُ بِأَبِيه، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" إِنَّ اللَّهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ، فَمَنْ كَانَ حَالِفًا، فَلْيَحْلِفْ بِاللَّهِ، أَوْ لِيَصْمُتْ "

Al-Hakam bin Al-Mubarak told us, Malik bin Anas told us, on the authority of Nafi’, on the authority of Ibn Umar: that the Messenger of God, may God bless him and grant him peace, realized Omar ibn al-Khattab was riding along, swearing by his father, and the Messenger of God, may God bless him and grant him peace, said: “Indeed, God forbids you from “Swear by your fathers; whoever swears, let him swear by God, or keep silent.”
