Sayyiduna Anas bin Malik (may Allah be pleased with him) says: The prayer of the Messenger of Allah (peace and blessings be upon him) used to be moderate, and the prayer of Sayyiduna Abu Bakr (may Allah be pleased with him) was also like that, until Sayyiduna Umar (may Allah be pleased with him) came, and he lengthened the standing (qiyam) in the Fajr prayer.
