Mishkat al-Masabih 3407
وَعَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ اللَّهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ مَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللَّهِ أَوْ ليصمت»
He reported God’s Messenger as saying, “God forbids you to swear by your fathers. If anyone swears he must swear by God, or keep silent.” (Bukhari and Muslim.)
