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.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ نَقْرَةِ الْغُرَابِ وَافْتِرَاشِ السَّبُعِ وَأَنْ يُوَطِّنَ الرَّجُلُ الْمَكَانَ فِي الْمَسْجِدِ كَمَا يُوَطِّنُ الْبَعِيرُ هَذَا لَفْظُ قُتَيْبَةَ  

The Messenger of Allah ﷺ forbade three things: "Pecking like a crow, resting one's forearms on the ground like a predator, and allocating the same place for prayer like a camel gets used to a certain place." (Using translation from Nasāʾī 1112)   

أَنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْ ثَلَاثٍ عَنْ نَقْرَةِ الْغُرَابِ وَعَنْ افْتِرَاشِ السَّبُعِ وَأَنْ يُوَطِّنَ الرَّجُلُ الْمُقَامَ قَالَ عُثْمَانُ فِي الْمَسْجِدِ كَمَا يُوَطِّنُ الْبَعِيرُ  

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. (Using translation from Abū Dāʾūd 862)   

«نَهَى رَسُولُ اللَّهِ ﷺ عَنْ نَقْرَةِ الْغُرَابِ وَافْتِرَاشِ السَّبُعِ وَأَنْ يُوَطِّنَ الرَّجُلُ الْمَكَانَ كَمَا يُوَطِّنُهُ الْبَعِيرُ»
