I saw that the Prophet ﷺ placed his knees (on the ground) before placing his hands when he prostrated himself. And when he stood up, he raised his hands before his knees.  

رَأَيْتُ النَّبِيَّ ﷺ إِذَا سَجَدَ وَضَعَ رُكْبَتَيْهِ قَبْلَ يَدَيْهِ وَإِذَا نَهَضَ رَفَعَ يَدَيْهِ قَبْلَ رُكْبَتَيْهِ  

When he prostrated himself, his knees fell on the ground before his hands had fallen. Hemmam said: This tradition has also been transmitted by ‘Asim b. Kulaib through a different chain of narrators to the same effect. And one of these two versions, and probably the version narrated by Muhammad b. Juhadah, has the words: When he stood up (after prostration), he stood up on his knees taking the support of his thighs.  

أَنَّ النَّبِيَّ ﷺ فَذَكَرَ حَدِيثَ الصَّلاَةِ قَالَ فَلَمَّا سَجَدَ وَقَعَتَا رُكْبَتَاهُ إِلَى الأَرْضِ قَبْلَ أَنْ تَقَعَ كَفَّاهُ قَالَ هَمَّامٌ وَحَدَّثَنَا شَقِيقٌ قَالَ حَدَّثَنِي عَاصِمُ بْنُ كُلَيْبٍ عَنْ أَبِيهِ عَنِ النَّبِيِّ ﷺ بِمِثْلِ هَذَا وَفِي حَدِيثِ أَحَدِهِمَا وَأَكْبَرُ عِلْمِي أَنَّهُ فِي حَدِيثِ مُحَمَّدِ بْنِ جُحَادَةَ وَإِذَا نَهَضَ نَهَضَ عَلَى رُكْبَتَيْهِ وَاعْتَمَدَ عَلَى فَخِذِهِ  

when one of you prostrates himself he must not kneel in the manner of camel, but should put down his hands before his knees.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا سَجَدَ أَحَدُكُمْ فَلاَ يَبْرُكْ كَمَا يَبْرُكُ الْبَعِيرُ وَلْيَضَعْ يَدَيْهِ قَبْلَ رُكْبَتَيْهِ  

The Prophet ﷺ said: (Does) one of you kneel down in his prayer as a camel kneels down (i.e. put his knees before his hands).  

قَالَ رَسُولُ اللَّهِ ﷺ يَعْمِدُ أَحَدُكُمْ فِي صَلاَتِهِ فَيَبْرُكُ كَمَا يَبْرُكُ الْجَمَلُ
