1Sahil B = ""The Shi‘ah believe that salvation requires the intercession of
Muhammad, his son-in-law Ali, his grandsons Hasan and Husayn, and the rest of the Prophet’s legitimate
successors, the Imams, who not only serve as humanity’s intercessors on the Last Days, but who further
function as the eternal executors (wali) of the divine Revelation."-No god but God, Reza Aslan "
