[Machine] I prayed behind the Messenger of Allah ﷺ , and I heard a man saying, "Allahu Akbar" (Allah is the Greatest) very loudly. "Alhamdulillah" (All praise be to Allah) repeatedly, "Tayyiban" (Pure) and "Mubarak" (Blessed) in it. The Messenger of Allah ﷺ said, "I saw the gates of heaven open for it, and twelve angels were leading it."  

صَلَّيْتُ خَلْفَ رَسُولِ اللهِ ﷺ فَسَمِعَ رَجُلًا يَقُولُ اللهُ أَكْبَرُ كَبِيرًا الْحَمْدُ لِلَّهِ كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ فَقَالَ رَسُولُ اللهِ ﷺ «رَأَيْتُهَا وَقَدِ ابْتَدَرَهَا اثْنَا عَشَرَ مَلَكًا وَفُتِحَتْ لَهَا أَبْوَابُ السَّمَاءِ»  

[Machine] It is narrated that the Prophet (PBUH) used to raise his hands and say the takbeer when he entered the prayer. Then he would cover himself with his garment and place his right hand over his left. When he intended to bow, he would say "like this with his garment" and he would take out his hands, then raise them and say the takbeer, and then he would bow. When he intended to prostrate, his knees would touch the ground before his palms. And when he prostrated, he would place his forehead between his palms and keep his elbows away from his sides. Hammam said, "The most knowledgeable among us is that in the narration of Muhammad ibn Juhaadah, when he stood up, he would stand on his knees and rely on his thighs."  

أَنَّ النَّبِيَّ ﷺ «كَانَ إِذَا دَخَلَ فِي الصَّلَاةِ رَفَعَ يَدَيْهِ وَكَبَّرَ ثُمَّ الْتَحَفَ بِثَوْبِهِ ثُمَّ وَضَعَ يَدَهُ الْيُمْنَى عَلَى الْيُسْرَى فَلَمَّا أَرَادَ أَنْ يَرْكَعَ قَالَ هَكَذَا بِثَوْبِهِ وَأخْرَجَ يَدَيْهِ ثُمَّ رَفَعَهُمَا وَكَبَّرَ وَرَكَعَ فَلَمَّا أَرَادَ أَنْ يَسْجُدَ وَقَعَتْ رُكْبَتَاهُ عَلَى الْأَرْضِ قَبْلَ كَفَّيْهِ فَلَمَّا سَجَدَ وَضَعَ جَبْهَتَهُ بَيْنَ كَفَّيْهِ وَجَافَى عَنْ إِبْطَيْهِ» قَالَ هَمَّامٌ وَأَكْبَرُ عِلْمِي أَنَّ فِي حَدِيثِ مُحَمَّدِ بْنِ جُحَادَةَ فَإِذَا نَهَضَ نَهَضَ عَلَى رُكْبَتَيْهِ وَاعْتَمَدَ عَلَى فَخِذَيْهِ
