8. Ali ibn Ibrahim has narrated from Salih ibn al-Sindy from Ja’far ibn Bashir from Aban from Fudayl from abu Ja’far who has said the following: “Abu Ja’far has said, ‘Islam is based on five principles: The prayer, al-Zakat (charity), fasting, al-Hajj and al-Wilayah. The call to no one of the other principles has been so emphatic as it was for al-Wilayah on the day of al-Ghadir (name of a place between Makka and Madina.)”’
