518 — Al-Firyābī informed us, saying: Ishāq ibn Sayyār al-Nasībī narrated to me, saying: Abd Allāh ibn Sālih narrated to us, saying: Mu‘āwiya—meaning Ibn Sālih—narrated to me, from Hakīm ibn ‘Umayr, who said: Umar ibn Abd al-Azīz was told, “Some people deny an aspect of divine predestination.” Umar replied, “Explain it to them and treat them gently until they return to the truth.” Someone then said, “Far from it, far from it, O Commander of the Faithful! They have made it into a religion and are calling people to it.” Umar was alarmed by this and said, “Those people deserve to have their tongues pulled out through the backs of their necks. Has any fly ever flown between heaven and earth except by a predetermined decree?”
