[Machine] Ibn Umar narrated that the Messenger of Allah ﷺ encountered Umar during one of his journeys and heard him saying, "And my father, and my father." So he said, "Verily, Allah forbids you from swearing by your fathers. So whoever swears, let him swear by Allah, and whoever does not, then let him remain silent."
عَنِ ابْنِ عُمَرَ أَدْرَكَ رَسُولُ اللهِ ﷺ عُمَرَ وَهُوَ فِي بَعْضِ أَسْفَارِهِ وَهُوَ يَقُولُ وَأَبِي وَأَبِي فَقَالَ إِنَّ اللهَ يَنْهَاكُمْ أَنْ تَحْلِفُوابِآبَائِكُمْ فَمَنْ كَانَ حَالِفًا فَلْيَحْلِفْ بِاللهِ وَإِلَّا فَلْيَصْمُتْ
