The Sunnah of our beloved Prophet
was made easy to practise.
The Messenger of Allah
, who adopted the Qur'an as his Guide, said, "Facilitate (religious matters) to people and do not make (things) difficult. Obey each other and do not differ (among yourselves)." - Bukhari.
So, basically, what the fuqaha have decided based upon the sunnah, that should be followed.
