Sayyiduna Rafi' bin Makith (may Allah be pleased with him), who had the honour of being present at al-Hudaybiyah, narrates that the Prophet (peace and blessings be upon him) said: "Treating parents well increases one's lifespan, and charity prevents an evil death."
Ahmad recorded it as part of a long hadith, from one of the descendants of Sayyiduna Rafi' (may Allah be pleased with him); others have named him as Muhammad bin Khalid bin Rafi'. So its narrators are thiqat (trustworthy) on the basis of the one who named him.
