Affan narrated to us, he said: Hammam narrated to us, he said: Zayd ibn Aslam narrated to us, from Ata ibn Yasar, from Abu Sa’id al-Khudri, he said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever lies about me—I think he said: 'intentionally'—then let him occupy his seat in the Fire."
