The Prophet (ﷺ) said, "Be straight in the prostrations and none of you should put his forearms on the ground (in the prostration) like a dog."
Sahih al-Bukhari Book 10, Hadith 216
← Previous Hadith Anas said, "I will leave no stone unturned in making you offer the prayer as I have seen the Prophet (ﷺ) making us offer it." Anas used to do a thing which I have not seen you doing. He used to stand after the bowing for such a long time that one would think that he had forgotten (the prostrations) and he used to sit in-between the prostrations so long that one would think that he had forgotten the second prostration.

Sahih al-Bukhari Book 10, Hadith 215 Next Hadith → I saw the Prophet (ﷺ) praying and in the odd rak`at, he used to sit for a moment before getting up.
