Hadith 1914
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Noble Prophet (peace and blessings be upon him) said: "When you are performing prayer, do not spread your arms the way beasts spread them. Support yourself on your palms and keep your arms away from your sides. When you do this, every part of your body will prostrate."
