I was with the Prophet ﷺ on a campaign, and I swore (an oath), No, by my father! A man called out from behind me: “Do not swear by your fathers.” And I saw that it was the Prophet ﷺ.
كُنْتُ مَعَ النَّبِيِّ ﷺ فِي غَزَاةٍ فَحَلَفْتُ لَا وَأَبِيفَهَتَفَ بِي رَجُلٌ مِنْ خَلْفِي فَقَالَ لَا تَحْلِفُوا بِآبَائِكُمْ فَإِذَا هُوَ النَّبِيُّ ﷺ
