Narrator:Abdullāh ibn ‘Umar
وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ رُمْحٍ، - وَاللَّفْظُ لَهُ - أَخْبَرَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ أَدْرَكَ عُمَرَ بْنَ الْخَطَّابِ فِي رَكْبٍ وَعُمَرُ يَحْلِفُ بِأَبِيهِ فَنَادَاهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَلاَ إِنَّ
اللَّهَ عَزَّ وَجَلَّ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ فَمَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ لِيَصْمُتْ "
‘Umar ibn al-Khattāb (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said:
"Indeed, Allah Almighty forbids you to swear by your forefathers." ‘Umar said: By Allah, I have never sworn by that since I heard that the Messenger of Allah (may Allah's peace and blessings be upon him) forbade it, neither deliberately nor reporting it from others.
