Ibn Umar reported that the Messenger of Allah (ﷺ), when he stood up for prayer, used to raise his hands apposite the shoulders and then recited takbir (Allah-o-Akbar), and when he was about to bow he again did like it and when he raised himself from the ruku' (bowing posture) he again did like it, but he did not do it at the time of raising his head from prostration.

This hadith has been transmitted with the same chain of transmitters by al. Zuhri as narrated by Ibn Juraij (who) said. When the Messenger of Allah (ﷺ) stood up for prayer, he raised hands (to the height) apposite the shoulders and then recited takbir.

Abu Qilaba reported that he saw Malik b. Huwairith raising his hands at the beginning of prayer and raising his hands before kneeling down, and raising his hands after lifting his head from the state of kneeling, and he narrated that the Messenger of Allah (ﷺ) used to do like this.

This hadith has been transmitted by Qatada with the same chain of transmitters that he saw the Messenger of Allah (ﷺ) doing this (i.e. raising his hands) till they were opposite the lobes of ears.
