Sahih Bukhari Volume 1, Book 10, Hadith 825

حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، قَالَ حَدَّثَنَا وُهَيْبٌ، عَنْ أَيُّوبَ، عَنْ أَبِي قِلاَبَةَ، قَالَ جَاءَنَا مَالِكُ بْنُ الْحُوَيْرِثِ فَصَلَّى بِنَا فِي مَسْجِدِنَا هَذَا فَقَالَ إِنِّي لأُصَلِّي بِكُمْ، وَمَا أُرِيدُ الصَّلاَةَ، وَلَكِنْ أُرِيدُ أَنْ أُرِيَكُمْ كَيْفَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم يُصَلِّي‏.‏ قَالَ أَيُّوبُ فَقُلْتُ لأَبِي قِلاَبَةَ وَكَيْفَ كَانَتْ صَلاَتُهُ قَالَ مِثْلَ صَلاَةِ شَيْخِنَا هَذَا ـ يَعْنِي عَمْرَو بْنَ سَلِمَةَ ـ قَالَ أَيُّوبُ وَكَانَ ذَلِكَ الشَّيْخُ يُتِمُّ التَّكْبِيرَ، وَإِذَا رَفَعَ رَأْسَهُ عَنِ السَّجْدَةِ الثَّانِيَةِ جَلَسَ وَاعْتَمَدَ عَلَى الأَرْضِ، ثُمَّ قَامَ‏

Narrated By Aiyub : Abu Qilaba said, "Malik bin Huwairith came to us and led us in the prayer in this mosque of ours and said, 'I lead you in prayer but I do not want to offer the prayer but just to show you how Allah's Apostle performed his prayers." I asked Abu Qilaba, "How was the prayer of Malik bin Huwairith?" He replied, "Like the prayer of this Sheikh of ours i.e. 'Amr bin Salima." That Sheikh used to pronounce the Takbir perfectly and when he raised his head from the second prostration he would sit for a while and then support himself on the ground and get up.
