Abu Hurairah reported,

When the Messenger of Allah ﷺ said the opening takbir for prayer, he would raise his hands level with his shoulders. He would do the same when he bowed, and the same when he rose from bowing, and the same when he stood up after the first two rakats.

Sahih

عن أبي هريرة أنه قال

كان رسول الله ﷺ إذا كبر للصلاة جعل يديه حذو منكبيه، وإذا ركع فعل مثل ذلك، وإذا رفع للسجود فعل مثل ذلك، وإذا قام من الركعتين فعل مثل ذلك.
