[Machine] While Umar ibn al-Khattab was walking in a caravan, he heard the Messenger of Allah ﷺ swearing by his father. The Messenger of Allah ﷺ then said, "Indeed, Allah forbids you from swearing by your fathers. So whoever swears, let him swear by Allah or remain silent."
بَيْنَمَا عُمَرُ بْنُ الْخَطَّابِ يَسِيرُ فِي رَكْبٍ فَسَمِعَهُ رَسُولُ اللهِ ﷺ وَهُوَ يَحْلِفُ بِأَبِيهِ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ اللهَ يَنْهَاكُمْ أَنْ تَحْلِفُوا بِآبَائِكُمْ فَمَنْ حَلَفَ فَلْيَحْلِفْ بِاللهِ أَوْ لِيَصْمُتْ»
