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
