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)  

أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ «نَهَى عَنْ ثَلَاثٍ عَنْ نَقْرَةِ الْغُرَابِ وَافْتِرَاشِ السَّبُعِ وَأَنْ يُوَطِّنَ الرَّجُلُ الْمَقَامَ لِلصَّلَاةِ كَمَا يُوَطِّنُ الْبَعِيرُ»
