Sayyiduna Ammar bin Yasir (may Allah be pleased with him) says: "By Allah! You love the Prophet (peace and blessings be upon him) more than those who saw him (peace and blessings be upon him) (the narrator is unsure, or perhaps the words are:) more than most of those who saw him (peace and blessings be upon him) (you love the Prophet (peace and blessings be upon him) more)."
Al-Bazzar and al-Tabarani recorded it; its chain contains a narrator, Abdullah bin Dawud al-Harrani, the brother of Abd al-Ghaffar, and I do not know him; the hadith of the rest of the narrators in al-Bazzar's chain is hasan (good).
