Sunan Ibn Majah Book 5, Hadith 862

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ: حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ: حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ جَعْفَرٍ: حَدَّثَنَا مُحَمَّدُ بْنُ عَمْرِو بْنِ عَطَاءٍ، عَنْ أَبِي حُمَيْدٍ السَّاعِدِيِّ، قَالَ سَمِعْتُهُ، وَهُوَ فِي عَشَرَةٍ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ، أَحَدُهُمْ أَبُو قَتَادَةَ بْنُ رِبْعِيٍّ قَالَ أَنَا أَعْلَمُكُمْ بِصَلاَةِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ كَانَ إِذَا قَامَ فِي الصَّلاَةِ اعْتَدَلَ قَائِمًا، وَرَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا مَنْكِبَيْهِ، ثُمَّ قَالَ ‏"‏ اللَّهُ أَكْبَرُ ‏"‏ ‏.‏ وَإِذَا أَرَادَ أَنْ يَرْكَعَ، رَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا مَنْكِبَيْهِ، فَإِذَا قَالَ ‏"‏ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ ‏"‏ ‏.‏ رَفَعَ يَدَيْهِ فَاعْتَدَلَ، فَإِذَا قَامَ مِنَ الثِّنْتَيْنِ، كَبَّرَ وَرَفَعَ يَدَيْهِ حَتَّى يُحَاذِيَ بِهِمَا مَنْكِبَيْهِ، كَمَا صَنَعَ حِينَ افْتَتَحَ الصَّلاَةَ ‏.‏

It was narrated that Muhammad bin `Amr bin `Ata’ said, concerning Abu Humaid As-Sa`di:“I heard him when he was among ten of the Companions of the Messenger of Allah (ﷺ), one of whom was Abu Qatadah bin Rib`i, saying: ‘I am the most knowledgeable of you about the prayer of the Messenger of Allah (ﷺ). When he stood up for prayer, he stood up straight and raised his hands until they were parallel to his shoulders, then he said: Allahu Akbar. When he wanted to bow in Ruku`, he raised his hands until they were parallel to his shoulders. When he said Sami` Allahu liman hamidah (Allah hears those who praise Him), he raised his hands and stood up straight. When he stood up after two Rak`ah, he said Allahu Akbar and raised his hands until they were parallel to his shoulders, as he did when he started the prayer.’”
