'Abdurrahman ibn Shabl said: "The Prophet prohibited pecking like a crow [i.e., while prostrating], imitating a lion's manner of sitting, and a man to pick a special place in the mosque [to pray] like a camel has his own place [to sit]." This is related by Ahmad, ibn Khuzaimah, ibn Hibban, and by al-Hakaim who calls it sahih.
