سنن ابن ماجه

It was narrated that Juwairiyah said: "The Messenger of Allah (ﷺ) passed by her when he prayed the morning prayer, or after he prayed the morning prayer, and she was remembering Allah. He came back when the sun had risen" - or he (one of the narrators) said, "at midday - and she was still doing that. He said: 'I have said four words, three times, since I left you, and they are greater and weigh more heavily than what you have said. They are: Subhan-Allahi 'adada khalqiha, Subhan-Allahi rida nafsihi, Subhan-Allahi zinata 'arshihi, Subhan-Allah midada kalimatihi (Glory is to Allah, as much as the number of His creation, glory is to Allah as much as pleases Him, glory is to Allah as much as the weight of His Throne, glory is to Allah as much as the ink of His words'."
