[Machine] On the day of Badr, I was standing beside the Prophet ﷺ, throwing arrows in front of him. I would place the arrow in the liver of the bow and say, "O Allah, shake their feet and frighten their hearts." The Prophet ﷺ would then say, "O Allah, answer the supplication of Sa'd."
يَوْمَ بَدْرٍ كُنْتُ أَرْمِي بَيْنَ يَدَيِ النَّبِيِّ ﷺ فَأَضَعُ السَّهْمَ فِي كَبِدِ الْقَوْسِ أَقُولُ اللهُمَّ زَلْزِلْ أَقْدَامَهُمْ وَأَرْعِبْ قُلُوبَهُمْ وَافْعَلْ بِهِمْ وَافْعَلْ فَيَقُولُ النَّبِيُّ ﷺ «اللهُمَّ اسْتَجِبْ لِسَعْدٍ»
