Whatever she said in dawn to forenoon (morning) these four words would surpass it

Juwairiyah (radhi Allaahu anha) reported that one day the Prophet, peace be upon him, left her apartment in the morning as she was busy observing her dawn prayer in her place of worship. He came back in the forenoon and she was still sitting there. The Prophet, peace be upon him, said to her, “You have been in the same place since I left you?” She said, “Yes.” Thereupon the Prophet, peace be upon him, said, “I recited four words three times after I left you and if these were to be weighed against what you have recited since morning these would outweigh them, and these words are:
سُبْحـانَ اللهِ وَبِحَمْـدِهِ عَدَدَ خَلْـقِه ، وَرِضـا نَفْسِـه ، وَزِنَـةَ عَـرْشِـه ، وَمِـدادَ كَلِمـاتِـه
Subhaanallaahi wa bihamdihi: ‘Adada khalqihi wa ridhaa nafsihi, wa zinata ‘arshihi wa midaada kalimaatihi.
Glory is to Allaah and praise is to Him, by the multitude of his creation, by His Pleasure, by the weight of His Throne, and by the extent of His Words (Recite 3 times in Arabic)
Muslim 4/2090
