Sa'd bin Abu Waqqas (May Allah be pleased with him) reported

The Messenger of Allah (ﷺ) and I went to see a woman. She had date- stones or pebbles in front of her, and she was counting and reciting Tasbih. ['Subhan-Allah' (Allah is free from imperfection)]. He said, "Shall I not inform you of what is easier or better than this for you?" You should say: 'Subhan-Allahi 'adada ma khalaqa fis-sama', wa subhan-Allahi 'adada ma khalaqa fil-ardi, wa subhan-Allahi 'adada ma baina dhalika, wa subhan-Allahi 'adada ma Huwa Khaliqun, wallahu Akbaru mithla dhalika, wal-hamdu lillahi mithla dhalika, wa la ilaha illallahu mithla dhalika, wa la hawla wa la quwwata illa billahi mithla dhalika (Subhan-Allah, equal to the number of what He created in the heaven; and Subhan-Allah, equal to the number of His creatures in the earth; and Subhan-Allah, equal to the number in between them; and Subhan-Allah equal to the number of those He will create).' Then say: 'Allahu Akbar' (Allah is Greatest) in the same way. Then say: 'Al-hamdu lillah' (praise be to Allah) in the same way. Then say: 'La ilaha illallah' (there is no true god except Allah) in the same way. Then say: 'La hawla wa la quwwata illa billah' (there is no change of a condition nor power except by Allah) in the same manner."
