muslim:391cMuḥammad b. al-Muthanná > Ibn Abū ʿAdī > Saʿīd > Qatādah Bihadhā al-Isnād > Raʾá Nabī Allāh ﷺ

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.  

مسلم:٣٩١cوَحَدَّثَنَاهُ مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ عَنْ سَعِيدٍ عَنْ قَتَادَةَ بِهَذَا الإِسْنَادِ

أَنَّهُ رَأَى نَبِيَّ اللَّهِ ﷺ وَقَالَ حَتَّى يُحَاذِيَ بِهِمَا فُرُوعَ أُذُنَيْهِ
