"I noticed the Prophet (ﷺ) was not there one night, so I started looking for him with my hand. My hand touched his feet and they were held upright, and he was prostrating and saying: 'I seek refuge in Your pleasure from Your anger, in Your forgiveness from Your punishment, and I seek refuge in You from You. I cannot praise You enough, You are as You have praised yourself.'"
Sunan an-Nasa'i Book 1, Hadith 170
