Musannaf Ibn Abi Shaybah 31160 — Those who used to say: O Turner

Sayyidah Aishah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) used to supplicate: "O Turner of hearts! Grant my heart firmness upon Your religion." I said: "O Messenger of Allah (peace and blessings be upon him)! You make this supplication?" He (peace and blessings be upon him) said: "O Aishah (may Allah be pleased with her)! Do you not know that the hearts of people, or he said: the heart of the son of Adam, is between two fingers of Allah Almighty? When Allah wills, He turns his heart towards guidance, and when He wills, He turns his heart towards misguidance."
