حَدَّثَنِي يَحْيَى، عَنْ مَالِك، عَنْ
نَافِعٍ ، عَنْ
عَبْدِ اللَّهِ بْنِ عُمَرَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَدْرَكَ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ، وَهُوَ يَسِيرُ فِي رَكْبٍ، وَهُوَ يَحْلِفُ بِأَبِيهِ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِنَّ
اللَّهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ فَمَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ لِيَصْمُتْ "
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said to Sayyiduna Umar bin Khattab (may Allah be pleased with him), while he was among the riders and was swearing by his father: The Messenger of Allah (peace and blessings be upon him) said: Allah, Glorified and Exalted is He, forbids you from swearing by your fathers. Whoever among you wishes to swear an oath, let him swear by Allah or remain silent.
