Hadith 5
The Book of Oaths and Vows
It was narrated from Salim, from his father, that he told him from 'Umar:
"The Messenger of Allah said: 'Allah forbids you to swear by your forefathers.'" 'Umar said: "By Allah, I never swore by them again, whether saying it for myself or reporting it of others."
أَخْبَرَنَا عَمْرُو بْنُ عُثْمَانَ بْنِ سَعِيدٍ، قَالَ أَنْبَأَنَا مُحَمَّدٌ، - وَهُوَ ابْنُ حَرْبٍ - عَنِ الزُّبَيْدِيِّ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، أَنَّهُ أَخْبَرَهُ عَنْ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ
إِنَّ اللَّهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ
