The Messenger of Allah ﷺ forbade three things, pecking like a crow, spreading the forearms on the ground like a beast of prey, and a man habitually claiming a fixed spot. Uthman added, "in the mosque, the way a camel claims its resting place."
حدثنا عثمان بن عمر حدثنا عبد الحميد ومحمد بن بكر قال أخبرنا عبد الحميد بن جعفر حدثني أبي عن تميم بن محمود
أن رسول الله ﷺ نهى عن ثلاث عن نقرة الغراب وعن افتراش السبع وأن يوطن الرجل المقام قال عثمان في المسجد كما يوطن البعير
Its isnad is daif because of Tamim bin Mahmud. Bukhari said, "There is doubt about him," and Aqeeli deemed him daif. Ibn Adi said, "He has nothing in hadith except from Abdul-Rahman bin Shibl, and his weakness is slight." The hadith was mentioned earlier under 15468.
