(Imām Bukhārī narrates): Muhammad ibn Muqātil narrated to us, he said: 'Abdullāh informed us, he said: Yūnus informed us, from al-Zuhrī, he said: Sālim ibn 'Abdullāh informed me, from 'Abdullāh ibn 'Umar, may Allāh be pleased with them both, he said:

I saw that the Messenger of Allāh ﷺ, when he stood up in prayer, would raise his hands until his two hands were level with his shoulders, and when he pronounced the takbīr for rukū', and when he raised his head from rukū', he did likewise, and he would say: "Sami'a Allāhu liman hamidah." And he did not do this in sajdah.
