Silsilah Sahihah

It is narrated from Sayyiduna Abdur Rahman bin Shibl (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade pecking in prostration like a crow (i.e., performing prostration hastily), and from spreading the arms in prostration like a beast, and also forbade that a person should reserve a particular spot in the mosque for himself as a camel does.
