Wilayat of Ameer al Momenin is related to our faith and all our actions ( including ebadaat (worships)and Mamelat (dealings) are depending upon the Wilayat of Ali (a.s).
While Taqleed is a system where you can find the guide lines of the Islamic Shariya in order to perform your ebadaat and Mamlaat in a correct and appropriate manner.
