Musannaf Ibn Abi Shayba 13:3001

Abu Bakr narrated to us, he said: Abd al-Salam ibn Sulayman narrated to us, from Mujalid, from al-Sha'bi, from Masruq, from Abdullah, who said: There is no judge who judges between people except that he will be gathered on the Day of Resurrection, and an angel will be holding him by the back of his neck until he stands with him over Hell. Then he will raise his head to the Most Merciful; if He says to him, "Cast him," he will cast him into a fall of forty autumns. He said: And Masruq said: "For me to judge for one day, upholding the truth and justice, is more beloved to me than a year in which I fight in the way of Allah."
