(18) باب {إِذْ هَمَّتْ طَائِفَتَانِ مِنْكُمْ أَنْ تَفْشَلاَ وَاللَّهُ وَلِيُّهُمَا وَعَلَى اللَّهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ}
Narrated Sa`d bin Abi Waqqas:
The Prophet (ﷺ) took out a quiver (of arrows) for me on the day of Uhud and said, "Throw (arrows); let my father and mother be sacrificed for you."
