1. Ali ibn Ibrahim ibn Hashim has narrated from his father from Hammad ibn ‘Isa from Hariz from Zurarah who has said the following: “Abu Ja’far عليه السلام, has said, ‘Islam is founded on five isssues. It is founded on Salat (prayer), zakat, al-Hajj, Fasting and al-Wilayat (belief in Divine Authority of ’A’immah). The Messenger of Allah has said, ‘Fasting is a shield against the fire of hell.”
