[Machine] The Prophet ﷺ used to raise his hands parallel to his shoulders when he began the prayer. And when he wanted to make the bowing (rak'ah) and when he raised his head from the bowing (rukoo'), he did not do so in any part of his prostration. And when he stood up from the two prostrations (sujood), he did the same. And this is also mentioned in one of the narrations from Wail ibn Hujr.
كَانَ النَّبِيُّ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَكَانَ لَا يَفْعَلُ ذَلِكَ فِي شَيْءٍ مِنْ سُجُودِهِ وَإِذَا قَامَ مِنَ السَّجْدَتَيْنِ مِثْلَ ذَلِكَ وَكَذَلِكَ هُوَ فِي إِحْدَى الرِّوَايَتَيْنِ عَنْ وَائِلِ بْنِ حُجْرٍ
