Mishkat al-Masabih 2301

Juwayriyah reported: The Prophet (peace be upon him) left her early in the morning after praying the dawn prayer while she was in her prayer place. He returned after midmorning and found her still sitting there. He asked, ‘Have you remained as I left you?’ She said, ‘Yes.’ The Prophet said, ‘After I left you, I said four phrases three times which, if weighed against everything you have said today, would outweigh it: “Glory be to God and praise be to Him, as many times as the number of His creation, to the extent of His good pleasure, equal to the weight of His Throne, and to the ink of His words.”’ Muslim transmitted it. The Arabic source grades it sahih (al-Albani).
