Musannaf Ibn Abi Shaybah 32396 — Book of Faith

Ibn Tawus (may Allah have mercy on him) reports from his father, Tawus (may Allah have mercy on him), and Muhill (may Allah have mercy on him) reports from Ibrahim (may Allah have mercy on him), that when the two of them (Tawus and Ibrahim) were asked about faith, they would say: "We believe in Allah, His angels, His Books and His Messengers."
