Sahih Muslim 391
Sahih Muslim · Book 4: The Book of Prayers · It Is Recommended To Raise The Hands Level With The Shoulders When Saying The Opening Takbir, When Bowing And When Rising From Bowing. But That Is Not To Be Done When Rising From The Prostration
وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ ، عَنْ سَعِيدٍ ، عَنْ قَتَادَةَ ، بِهَذَا الإِسْنَادِ أَنَّهُ رَأَى نَبِيَّ اللَّهِ صلى الله عليه وسلم وَقَالَ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ .
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.
