The Messenger of Allah (ﷺ) prohibited to peck like a crow, and to spread (the forearms) like a wild beast, and to fix a place in the mosque like a camel which fixes its place. These are the wordings of Qutaybah.
Sunan Abi Dawud Book 2, Hadith 472
← Previous Hadith Then perform ablution in a way Allah, the exalted, has command you, then say the shahadah and get up and say the takbir. Then if you know any of the Qur’an, recite it; otherwise say: “Praise be to Allah”; “Allah is most great”; “ There is no god but Allah” He ( the narrator) also said in this version: If some defect remains in this, that detect will remain in your prayer.

Sunan Abi Dawud Book 2, Hadith 471 Next Hadith → Salim al-Barrad said: We came to AbuMas'ud Uqbah ibn Amr al-Ansari and said to him: Tell us about the prayer of the Messenger of Allah (ﷺ).

He stood up before us in the mosque and said the takbir. When he bowed, he placed his hands upon his knees and put his fingers below, and kept his elbows (arms) away from his sides, so everything returned properly to its place. Then he said: "Allah listens to him who praises Him"; then he stood up so that everything returned properly to its place; then he said the takbir and prostrated and put the palms of his hands on the ground; he kept his elbow (arms) away from his sides, so that everything returned to its proper place. Then he raised his head and sat so that everything returned to its place; he then repeated it in a similar way. Then he offered four rak'ahs of prayer like this rak'ah and completed his prayer.

Then he said: Thus we witnessed the Messenger of Allah (ﷺ) offering his prayer.
