The Wilayat Of Allah (s.w.t.)

Sadouq narrated from Husain bin Ahmad bin Edris, from his father, from Ibrahim bin Hashim, from Mohammad bin Senan, from Abu JaroodZiyad bin Monthir, from Saeed bin Jubayr, from Ibn Abbas, from the Messenger of Allah (s.a.w.a.), who said:

The Wilayat of Ali bin AbiTaleb is the Wilayat of Allah (s.w.t.). Loving Ali bin AbiTaleb is worshipping Allah (s.w.t.). Following him is made mandatory by Allah (s.w.t.). His friends are the friends of Allah (s.w.t.), and his enemies are the enemies of Allah (s.w.t.) . His group is the group of Allah(s.w.t.) , and his peace is the peace of Allah.
