حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ عَنْ مَالِکٍ عَنْ نَافِعٍ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَدْرَکَ عُمَرَ بْنَ الْخَطَّابِ وَهُوَ يَسِيرُ فِي رَکْبٍ يَحْلِفُ بِأَبِيهِ فَقَالَ أَلَا إِنَّ اللَّهَ يَنْهَاکُمْ أَنْ تَحْلِفُوا بِآبَائِکُمْ مَنْ کَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ لِيَصْمُتْ
صحیح بخاری · Hadith 6646
Narrated Ibn `Umar: Allah's Apostle met `Umar bin Al-Khattab while the latter was going with a group of camel-riders, and he was swearing by his father. The Prophet said, "Lo! Allah forbids you to swear by your fathers, so whoever has to take an oath, he should swear by Allah or keep quiet."
