When the Messenger of Allah ﷺ prayed he would raise his hands-when he said the Takbir- until they were parallel to his ears, and when he wanted to bow and when he raised his head from bowing.  

عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا صَلَّى رَفَعَ يَدَيْهِ حِينَ يُكَبِّرُ حِيَالَ أُذُنَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ  

The Prophet ﷺ used to raise his hands when he began to pray, when he wanted to bow, when he raised his head from bowing, and when he stood up after the first two rak'ahs, he would raise his hands likewise, level with his shoulders.  

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَرْفَعُ يَدَيْهِ إِذَا دَخَلَ فِي الصَّلاَةِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَإِذَا قَامَ مِنَ الرَّكْعَتَيْنِ يَرْفَعُ يَدَيْهِ كَذَلِكَ حَذْوَ الْمَنْكِبَيْنِ  

[Machine] On the authority of Malik ibn al-Huwayrith, who was one of the companions of the Prophet ﷺ , he said: The Prophet ﷺ used to raise his hands when he entered into prayer, and when he went into prostration, and when he lifted his head from the bowing position until his ears.  

عَنْ مَالِكِ بْنِ الْحُوَيْرِثِ وَكَانَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ قَالَ كَانَ النَّبِيُّ ﷺ يَرْفَعُ يَدَيْهِ إِذَا دَخَلَ فِي الصَّلَاةِ وَإِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ إِلَى أُذُنَيْهِ  

[Machine] Certainly, the Prophet ﷺ used to "when he performed the takbeer, he would raise his hands until they were level with his ears, and when he intended to bow, and when he raised his head from bowing."  

أَنَّ النَّبِيَّ ﷺ كَانَ «إِذَا كَبَّرَ رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ أُذُنَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ»  

"عَنْ عَلِىٍّ: أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَرْفَعُ يَدَيْهِ إِذَا كَبَّرَ فِي الصَّلَاةِ حَذْوَ مِنكبَيْهِ، وَإِذا أَرَادَ أَنْ يَرْكَعَ، وَإذا رَفَعَ رَأسَهُ مِنَ الرُّكُوعِ، وَإِذَا قَامَ فِي الرَّكْعَةِ فَعَلَ مِثْلَ ذَلِكَ".
