'Aishah (May Allah be pleased with her) reported:
One night I missed the Messenger of Allah (ﷺ) from his bed. I searched for him. When I found him he was in bowing or prostrating posture and was reciting: Subhanaka wa bi hamdika. La ilaha illa Anta (You are free from imperfection and I begin praising You. There is no true god except You)."Another narration is: My hand fell over his feet while he was in prostration with his feet erect. He was supplicating: "Allahumma inni a'udhu biridaka min sakhatika, wa bi-mu'afatika min 'uqubatika, wa a'udhu bika minka, la uhsi thana'an 'alaika, Anta kama athnaita 'ala Nafsika (O Allah! I seek protection against Your Wrath in Your Pleasure. I seek protection in Your Pardon against Your chastisement, I am not capable of enumerating praise of You. You are as You have lauded Yourself)."
