“May my father and my mother be ransomed for you, O Messenger of Allah (ﷺ)! Which speech is most beloved to Allah ?” So he said: “That which Allah selected for His angels (to say): ‘Glory to my Lord, and with His praise. Glory to my Lord, and with His praise (Subḥāna rabbī wa biḥamdihi, subḥāna rabbī wa biḥamdihi).’”
Jami` at-Tirmidhi Book 48, Hadith 224
