Sunan Abi Dawud Book 2, Hadith 450
when one of you prostrates himself he must not kneel in the manner of camel, but should put down his hands before his knees.
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.
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).
