"When the Prophet (ﷺ) raised his head from bowing, he said: 'Allahumma Rabbana wa lakal-hamd (O Allah, our Lord and to You be the praise).'"
Sunan an-Nasa'i Book 12, Hadith 32
← Previous Hadith When the Messenger of Allah (ﷺ) started to pray, he raised his hands until they were in level with his shoulders, and when he said the takbir before bowing, and when he raised his head from bowing he raised (his hands) likewise, and said: "Sami Allahu liman hamidah Rabbana wa lakal-hamd (Allah hears the one who praises Him; Our Lord, and to You be praise)," and he did not do that when prostrating.

Sunan an-Nasa'i Book 12, Hadith 31 Next Hadith → The Prophet (ﷺ) fell from a horse onto his right side, and they entered upon him to visit him. The time for prayer came, and when he had finished praying he said: "The Imam is appointed to be followed, so when he bows, then bow, and when he stands up, then stand up, and when he says: 'Sami' Allahu liman hamidah (Allah hears the one who praises Him)' then say: 'Rabbana wa lakal-hamd (Our Lord, and to You be the praise).'"
