249 — Hāshim ibn al-Hārith narrated to me. He said: Abdullāh ibn Bakr al-Sahmī narrated to us. He said: Muhammad ibn al-Nuʿmān narrated to me, tracing the hadith back to the Prophet (peace and blessings be upon him), who said: “Whoever visits the grave of both his parents, or of either one of them, once every Friday will be forgiven and recorded as one who was dutiful to his parents.”
