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."  

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنْ ثَلاَثٍ عَنْ نَقْرَةِ الْغُرَابِ وَافْتِرَاشِ السَّبُعِ وَأَنْ يُوَطِّنَ الرَّجُلُ الْمُقَامَ لِلصَّلاَةِ كَمَا يُوَطِّنُ الْبَعِيرُ
