Musnad Ahmad 15358

Translation

✧ Zubayd and Salamah informed me that they heard from Ibn Abd al-Rahman ibn Abzah, from his father, that the Prophet ﷺ used to perform the night prayer with the recitation of the Surah of "Glorify the name of your Lord, the Most High," and the Surahs of "O disbelievers" and "Say: He is Allah, the One." And when he finished the prayer, he would say, "Exalted is the King, the Holy One," three times, raising his voice in the last one.
