Sahih al-Bukhari 64:72

Narrated Jubair bin Mut'im:

I heard the Prophet (ﷺ) reciting Surat-at-Tur in Maghrib prayer, and that was at a time when belief was first planted in my heart. The Prophet (ﷺ) while speaking about the war prisoners of Badr, said, "Were Al-Mutim bin Adi alive and interceded with me for these filthy people, I would definitely forgive them for his sake."
