Musannaf Ibn Abi Shaybah 34059 — Reports on the affair of Dawud

Al-Ahnaf bin Qays reports from the Prophet (peace and blessings be upon him) that Dawud (peace be upon him) said: "O Lord, the Children of Israel make supplication to You by means of Ibrahim, Ishaq and Ya'qub. O Allah, make me the fourth among them." So Allah Almighty revealed to him: "Ibrahim was thrown into the fire because of Me, and he was patient, and such a trial has not come to you. And Ishaq sacrificed his life for Me and was patient, and this trial too has not come to you. And I took away the beloved of Ya'qub until his eyes turned white, and he too was patient, and this trial too has not come to you."
