Ali bin Abu Talib reported,

It is narrated from the Messenger of Allah ﷺ that whenever he stood to perform the obligatory prayer, he would say the takbir and raise his hands level with his shoulders. He would do the same when he finished his recitation and was about to bow, and he would do it again when he rose from bowing. He would not raise his hands at any point during his prayer while he was seated. When he rose from the two prostrations, he would likewise raise his hands and say the takbir.

عن علي بن أبي طالب

عن رسول الله ﷺ أنه إذا قام إلى الصلاة المكتوبة كبر ورفع يديه حذو منكبيه، ويصنع مثل ذلك إذا قضى قراءته، وإذا أراد أن يركع، ويصنعه إذا رفع من الركوع، ولا يرفع يديه في شيء من صلاته وهو قاعد، وإذا قام من السجدتين رفع يديه كذلك وكبر.
