Riyad as-Salihin — Hadith #46422

On the authority of Saad bin Abi Waqqas, may God be pleased with him, he entered with the Messenger of God, may God’s prayers and peace be upon him, to see a woman, and in her hands were stones - or pebbles - with which to recite the tasbih, and he said: “I will tell you what is easier for you than this - or better.” So he said: “Glory be to God, the number of what He created in the heavens, and Glory be to God, the number of what He created on earth, and Glory be to God, the number of what is in between, and Glory be to God, the number of what He is the Creator, and God is greater like that, and praise be to God like that. That, and there is no god but God like that That, and there is no power nor strength except with God like that.” ((Narrated by Al-Tirmidhi and said: A good hadith)).
