Since I 7 years old, I have kept the daily five prayers until now. Sunna has nothing to do with prayers. According to the Quran, all Muslim rituals belong to the old religion of Abraham. This includes prayers, charities, fasting and pilgrimage. Mohammed was a follower of Abraham. Arabs before Mohammed and during his life used to pray and fast and make pilgrimage as they inherited it from their father Abraham, but they used to mix it with believing in saints and idols, the same as Muslims are doing now. The Quran was revealed not to invent a new religion but to reform the inherited Religion of Abraham.
