Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings be upon him) saying: "There will be a man in my nation who will speak after death."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Mansur except Sharik; Ibrahim bin al-Hasan al-Tha'labi is alone in narrating it."
