The Mother of the Believers, Juwairiyah bint Al-Harith (RadhiAllahu 'anha) reported: The Prophet (sal-Allaahu 'alayhe wa sallam) came out from my apartment in the morning as I was busy in performing the dawn prayer. He came back in the forenoon and found me sitting there. The Prophet (sal-Allaahu 'alayhe wa sallam) said, "Are you still in the same position as I left you.'' I replied in the affirmative. Thereupon the Prophet ﷺ said, "I recited four words three times after I had left you. If these are to be weighed against all you have recited since morning, these will be heavier. " Say:
سُبْحَانَ اللَّهِ وَبِحَمْدِهِ عَدَدَ خَلْقِهِ، وَرِضَا نَفْسِهِ، وَزِنَةَ عَرْشِهِ، وَمِدَادَ كَلِمَاتِهِ
How perfect Allaah is and I praise Him by the number of His creation and His pleasure, and by the weight of His throne, and the ink of His words.
Subhaanallaahi wa bihamdihi, 'Adada khalqihi, wa ridhaa nafsihi, wa zinata 'arshihi wa midaada kalimaatihi.
