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

Ibn Umar reported that the Messenger of Allah ﷺ, when he stood up for prayer, used to raise his hands apposite the shoulders and then recited takbir (Allah-o-Akbar), and when he was about to bow he again did like it and when he raised himself from the ruku' (bowing posture) he again did like it, but he did not do it at the time of raising his head from prostration.

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا قَامَ لِلصَّلاَةِ رَفَعَ يَدَيْهِ حَتَّى تَكُونَا حَذْوَ مَنْكِبَيْهِ ثُمَّ كَبَّرَ فَإِذَا أَرَادَ أَنْ يَرْكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَلاَ يَفْعَلُهُ حِينَ يَرْفَعُ رَأْسَهُ مِنَ السُّجُودِ

He saw the Prophet of Allah ﷺ raise his hands when he started to pray, and he narrated a similar report and added: "When he bowed he did likewise, and when he raised his head from bowing he did likewise, and when he raised his head from prostration he did likewise."

أَنَّ نَبِيَّ اللَّهِ ﷺ كَانَ إِذَا دَخَلَ فِي الصَّلاَةِ فَذَكَرَ نَحْوَهُ وَزَادَ فِيهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ فَعَلَ مِثْلَ ذَلِكَ

When the Prophet of Allah ﷺ started to pray, he raised his hands, and when he bowed, he did likewise, and when he raised his head from bowing he did likewise, and when he raised his head from prostration, he did likewise, meaning he raised his hands.

أَنَّ نَبِيَّ اللَّهِ ﷺ كَانَ إِذَا دَخَلَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ فَعَلَ مِثْلَ ذَلِكَ كُلَّهُ يَعْنِي رَفْعَ يَدَيْهِ

“When the Prophet ﷺ stood up to offer a prescribed prayer, he said Allahu Akbar and raised his hands until they were parallel to his shoulders. When he wanted to bow he did likewise; when he raised his head from bowing he did likewise; and when he stood up after the two prostrations he did likewise.”*

كَانَ النَّبِيُّ ﷺ إِذَا قَامَ إِلَى الصَّلاَةِ الْمَكْتُوبَةِ كَبَّرَ وَرَفَعَ يَدَيْهِ حَتَّى يَكُونَا حَذْوَ مَنْكِبَيْهِ وَإِذَا أَرَادَ أَنْ يَرْكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا قَامَ مِنَ السَّجْدَتَيْنِ فَعَلَ مِثْلَ ذَلِكَ

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)

كَانَ رَسُولُ اللهِ ﷺ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَذْوَ مَنْكِبَيْهِ وَإِذَا رَكَعَ صَنَعَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ صَنَعَ مِثْلَ ذَلِكَ وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ قَالَ رَبَّنَا وَلَكَ الْحَمْدُ وَلَا يَصْنَعُ مِثْلَ ذَلِكَ فِي السُّجُودِ

It was narrated that Malik bin Huwairith said that when the Messenger of Allah ﷺ said Allahu Akbar, he would raise his hands until they were close to his ears; when he bowed in Ruku’ he did likewise, and when he raised his head from Ruku’ he did likewise. (Using translation from Ibn Mājah 859)

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا كَبَّرَ رَفَعَ يَدَيْهِ حَتَّى يَجْعَلَهُمَا قَرِيبًا مِنْ أُذُنَيْهِ وَإِذَا رَكَعَ صَنَعَ مِثْلَ ذَلِكَوَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ 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

[Machine] "I saw the Messenger of Allah ﷺ begin the takbeer in prayer, and he raised his hands until they were level with his shoulders. Then, when he said the takbeer for the bowing, he did the same. Then he said, 'Allah listens to the one who praises Him,' and he did the same. Then he said, 'Our Lord, praise is due to You,' and he did the same."

«رَأَيْتُ رَسُولَ اللهِ ﷺ افْتَتَحَ التَّكْبِيرَ فِي الصَّلَاةِ فَرَفَعَ يَدَيْهِ حَتَّى جَعَلَهُمَا حَذْوَ مَنْكِبَيْهِ ثُمَّ إِذَا كَبَّرَ لِلرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ» ثُمَّ قَالَ «سَمِعَ اللهُ لِمَنْ حَمِدَهُ» فَفَعَلَ مِثْلَ ذَلِكَ ثُمَّ قَالَ «رَبَّنَا لَكَ الْحَمْدُ فَفَعَلَ مِثْلَ ذَلِكَ»

[Machine] The Messenger of Allah ﷺ used to raise his hands to the level of his shoulders when he would say the takbeer in prayer and when he would bow, he would do the same. And when he would raise his head, he would also do the same. And when he would say "Allah hears the one who praises Him," he would say "Our Lord, to You is the praise" and he would do the same. And he would not do this during prostration.

أَنَّ رَسُولَ اللهِ ﷺ «كَانَ إِذَا كَبَّرَ فِي الصَّلَاةِ رَفَعَ يَدَيْهِ حِذَاءَ مَنْكِبَيْهِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ فَعَلَ مِثْلَ ذَلِكَ» وَإِذَا قَالَ «سَمِعَ اللهُ لِمَنْ حَمِدَهُ» قَالَ «رَبَّنَا لَكَ الْحَمْدُ وَفَعَلَ مِثْلَ ذَلِكَ وَلَا يَفْعَلُ فِي السُّجُودِ»

When the Prophet of Allah ﷺ started to pray, he raised his hands, and when he bowed, he did likewise, and when he raised his head from bowing he did likewise, and when he raised his head from prostration, he did likewise, meaning he raised his hands. (Using translation from Nasāʾī 1143)

أَنَّ نَبِيَّ اللهِ ﷺ كَانَ «إِذَا دَخَلَ فِي الصَّلَاةِ وَإِذَا رَكَعَ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ فَعَلَ مِثْلَ ذَلِكَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ فَعَلَ مِثْلَ ذَلِكَ كَأَنَّهُ يَعْنِي رَفَعَ يَدَيْهِ»
