How sound is the supplication: "Glory be to Allah and with His praise, as many times as there was and as many times as there will be; and glory be to Allah as many times as there are movements and stillness"?

There is no harm in saying: "Subhanallah wa bihamdihi adada ma kana wa adada ma yakun, wa Subhanallah adada al-harakat wa as-sukoon (Glory be to Allah and with His praise, as many as there have been and as many as there will be; and glory be to Allah as many as the movements and stillness)," even though it is better to limit oneself to what has been mentioned in the Sunnah, such as the Prophet, peace and blessings be upon him, saying: "Subhanallah wa bihamdihi adada khalqihi, wa rida nafsihi, wa zinata arshihi, wa midada kalimatihi (Glory be to Allah and with His praise, as many as His creation, as much as pleases Him, as much as the weight of His Throne, and as much as the ink of His words)."
