(18) باب {إِذْ هَمَّتْ طَائِفَتَانِ مِنْكُمْ أَنْ تَفْشَلاَ وَاللَّهُ وَلِيُّهُمَا وَعَلَى اللَّهِ فَلْيَتَوَكَّلِ الْمُؤْمِنُونَ}
Narrated Ibn Al Musaiyab:
Sa`d bin Abi Waqqas said, "Allah's Messenger (ﷺ) mentioned both his father and mother for me on the day of the battle of Uhud." He meant when the Prophet (ﷺ) said (to Sa`d) while the latter was fighting. "Let my father and mother be sacrificed for you!"
