Musannaf Ibn Abi Shaybah 32422 — Book of Faith

Yusuf bin Maymun (may Allah have mercy on him) said: I said to Ata (may Allah have mercy on him): "Among us there are people whom we count among the righteous. If we say: We are believers, they find fault with us for it." He said: Ata (may Allah have mercy on him) said: "We are indeed believers and Muslims, and this is how we found the Companions of the Messenger of Allah (peace and blessings be upon him) speaking."
