When the Prophet (ﷺ) stood up following two prostrations, he would say the takbir and raise his hands until they were level with his shoulders, as he had done at the beginning of the prayer.

← Previous Hadith "Ali bin Abi Talib prayed, and he said the takbir every time he went down and came up, in all movements of the prayer. 'Imran bin Husain said: 'This reminds me of the prayer of the Messenger of Allah (ﷺ).'"

Sunan an-Nasa'i Book 13, Hadith 2 Next Hadith → The Prophet (ﷺ) used to raise his hands when he began to pray, when he wanted to bow, when he raised his head from bowing, and when he stood up after the first two rak'ahs, he would raise his hands likewise, level with his shoulders.
