Musnad Ahmad 1158:0

It was narrated from Juwayriyah bint al-Harith ibn Abi Dirar that the Prophet (ﷺ) entered upon her while she was in her prayer place, and he went out. Then he returned after the sun had risen high, and she was still sitting there. He said: "Are you still in the same state as I left you?" She said: "Yes." The Prophet (ﷺ) said: "I have said four words three times after you, which, if they were weighed against what you have said since the beginning of the day, they would outweigh them: 'Glory be to Allah and His praise, by the number of His creation, by the pleasure of His Self, by the weight of His Throne, and by the ink of His words' (Subhan Allah wa bi-hamdihi, 'adada khalqihi, wa rida nafsihi, wa zinata 'arshihi, wa midada kalimatihi)."
