Sayyiduna Abu Umamah bin Sahl bin Hunayf (may Allah be pleased with him) narrates: My father said: "O my son, I remember about us on the day of Badr that one of us would point his sword at a polytheist's head, and his head would fall off from his body before the sword (or the attacker) reached him."
Al-Tabarani recorded it. Its chain contains Muhammad bin Yahya al-Iskandarani; Ibn Yunus said: He narrated munkar (objectionable) reports.
