I saw that whenever Messenger of Allah ﷺ stood for the prayer, he used to raise both his hands up to the shoulders, and used to do the same on saying the Takbir for bowing and on raising his head from it and used to say, "Samiʿa l-lahu liman hamidah". But he did not do that (i.e. raising his hands) in prostrations.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا قَامَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ حَتَّى يَكُونَا حَذْوَ مَنْكِبَيْهِ وَكَانَ يَفْعَلُ ذَلِكَ حِينَ يُكَبِّرُ لِلرُّكُوعِ وَيَفْعَلُ ذَلِكَ إِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَيَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ وَلاَ يَفْعَلُ ذَلِكَ فِي السُّجُودِ  

I saw Messenger of Allah ﷺ opening the prayer with the Takbir and raising his hands to the level of his shoulders at the time of saying the Takbir, and on saying the Takbir for bowing he did the same; and when he said, "Samiʿa l-lahu liman hamidah ", he did the same and then said, "Rabbana wa laka lhamd." But he did not do the same on prostrating and on lifting the head from it."  

رَأَيْتُ النَّبِيَّ ﷺ افْتَتَحَ التَّكْبِيرَ فِي الصَّلاَةِ فَرَفَعَ يَدَيْهِ حِينَ يُكَبِّرُ حَتَّى يَجْعَلَهُمَا حَذْوَ مَنْكِبَيْهِ وَإِذَا كَبَّرَ لِلرُّكُوعِ فَعَلَ مِثْلَهُ وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَعَلَ مِثْلَهُ وَقَالَ رَبَّنَا وَلَكَ الْحَمْدُ وَلاَ يَفْعَلُ ذَلِكَ حِينَ يَسْجُدُ وَلاَ حِينَ يَرْفَعُ رَأْسَهُ مِنَ السُّجُودِ  

I saw the Messenger of Allah ﷺ when he said the opening Takbir of the prayer, raise his hands until they were level with his shoulders. When he said the Takbir before bowing he did likewise, and when he said: 'Sami Allahu liman hamidah (Allah hears those who praise Him),' he did likewise, then he said: 'Rabbana wa lakal-hamd (Our Lord, to You be praise).' But he did not do that when he prostrated or when he raised his head from prostration.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا افْتَتَحَ التَّكْبِيرَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ حِينَ يُكَبِّرُ حَتَّى يَجْعَلَهُمَا حَذْوَ مَنْكِبَيْهِ وَإِذَا كَبَّرَ لِلرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ ثُمَّ إِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَعَلَ مِثْلَ ذَلِكَ وَقَالَ رَبَّنَا وَلَكَ الْحَمْدُ وَلاَ يَفْعَلُ ذَلِكَ حِينَ يَسْجُدُ وَلاَ حِينَ يَرْفَعُ رَأْسَهُ مِنَ السُّجُودِ  

"I saw the Messenger of Allah ﷺ, when he stood to pray, raise his hands until they were in level with his shoulders, then he said the takbir. He did that when he said the Takbir before bowing, and he did that when he raised his head from bowing and said: 'Sami Allahu liman hamidah (Allah hears those who praise Him).' Bu he did not do that during the prostration."  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ إِذَا قَامَ إِلَى الصَّلاَةِ رَفَعَ يَدَيْهِ حَتَّى تَكُونَا حَذْوَ مَنْكِبَيْهِ ثُمَّ يُكَبِّرُ قَالَ وَكَانَ يَفْعَلُ ذَلِكَ حِينَ يُكَبِّرُ لِلرُّكُوعِ وَيَفْعَلُ ذَلِكَ حِينَ يَرْفَعُ رَأْسَهُ مِنَ الرُّكُوعِ وَيَقُولُ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ وَلاَ يَفْعَلُ ذَلِكَ فِي السُّجُودِ  

When the Messenger of Allah ﷺ uttered the takbir (Allah is most great) for prayer (in the beginning), he raised his hands opposite to his shoulders; and when he bowed, he did like that; and when he raised his head to prostrate, he did like that; and when he got up at the end of two rak'ahs, he did like that.  

أَنَّهُ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ إِذَا كَبَّرَ لِلصَّلاَةِ جَعَلَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ لِلسُّجُودِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا قَامَ مِنَ الرَّكْعَتَيْنِ فَعَلَ مِثْلَ ذَلِكَ  

I saw the Messenger of Allah ﷺ when he said the opening Takbir of the prayer, raise his hands until they were level with his shoulders. When he said the Takbir before bowing he did likewise, and when he said: 'Sami Allahu liman hamidah (Allah hears those who praise Him),' he did likewise, then he said: 'Rabbana wa lakal-hamd (Our Lord, to You be praise).' But he did not do that when he prostrated or when he raised his head from prostration. (Using translation from Nasāʾī 876)   

كَانَ النَّبِيُّ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ فَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَقَالَ «سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ» وَلَا يَفْعَلُ ذَلِكَ فِي السُّجُودِ  

that when the Messenger of Allah ﷺ started to pray, he would raise his hands in level with his shoulders, and when he bowed and when he raised his head from bowing, he would raise them likewise and say "Sami Allahu liman hamidah, Rabbana wa lakal-hamd (Allah hears those who praise Him, our Lord, to You be praise." And he did not do that when he prostrated. (Using translation from Nasāʾī 878)  

«أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا كَبَّرَ لِلرُّكُوعِ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ رَفَعَهُمَا كَذَلِكَ أَيْضًا وَقَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ رَبَّنَا وَلَكَ الْحَمْدُ وَكَانَ لَا يَفْعَلُ ذَلِكَ فِي السُّجُودِ»

But he did not do the same on prostrating and on lifting the head from it." (Using translation from Bukhārī 738)  

رَأَيْتُ رَسُولَ اللهِ ﷺ إِذَا افْتَتَحَ التَّكْبِيرَ فِي الصَّلَاةِ رَفَعَ يَدَيْهِ حِينَ يُكَبِّرُ حَتَّى يَجْعَلَهُمَا حَذْوَ مَنْكِبَيْهِ وَإِذَا كَبَّرَ لِلرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ ثُمَّ إِذَا قَالَ «سَمِعَ اللهُ لِمَنْ حَمِدَهُ» فَعَلَ مِثْلَ ذَلِكَ وَقَالَ «رَبَّنَا وَلَكَ الْحَمْدُ» وَلَا يَفْعَلُ ذَلِكَ حِينَ يَسْجُدُ وَلَا حِينَ يَرْفَعُ رَأْسَهُ مِنَ السُّجُودِ
