Hadith 1359
Qatadah (may Allah have mercy on him) said: I heard Sayyiduna Anas bin Malik (may Allah be pleased with him) say, the Messenger of Allah (peace and blessings of Allah be upon him) said: "Maintain moderation in prostration and do not spread your hands like a dog."
Hadith 1360
Sayyiduna Abdur Rahman bin Shibl Ansari رضي الله عنه said: The Messenger of Allah صلى الله عليه وسلم forbade spreading the arms (in prostration) like a beast of prey, pecking like a crow (i.e., performing prostration quickly), and designating a specific spot in the mosque as a camel designates its place.
