Sayyiduna Jabir bin Samurah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) used to pray the prayers much like your prayers today, but he (peace and blessings be upon him) kept them light, and his (peace and blessings be upon him) prayer was lighter than your prayer. In the Fajr prayer he (peace and blessings be upon him) used to recite Surah al-Waqi'ah and surahs like it.
