Abdullah bin Umar reported,

While we were praying with the Messenger of Allah ﷺ, a man from the congregation said, "Allah is most great, abundant praise be to Allah, and glory be to Allah morning and evening."The Messenger of Allah ﷺ asked, "Who said such and such words?"A man from the congregation replied, "I did, Messenger of Allah."He said, "I marveled at them. The gates of heaven were opened for them."

عن ابن عمر قال

بينما نحن نصلي مع رسول الله ﷺ إذ قال رجل من القوم: الله أكبر كبيرا، والحمد الله كثيرا، وسبحان الله بكرة وأصيلا، فقال رسول الله ﷺ: من القائل كلمة كذا وكذا؟ فقال رجل من القوم: أنا يا رسول الله! قال: عجبت لها، فتحت لها أبواب السماء.
