Principles of Islam and Imaan

بسم الله الواحد القهار

Sheikh Al-Kulayni:

Ali ibn Ibrahim has narrated from Muhammad ibn ’Isa from Yunus ibn ‘Abd al-Rahman from ’Ajlan ibn Salih who has said the following:
“I requested abu ‘Abd Allah, recipient of divine supreme covenant, ‘Teach me, please, the principles of beliefs. The Imam said, ‘They are: to testify and affirm that there is no one who deserves to be worshipped except Allah, to testify and affirm that Muhammad is the Messenger of Allah and to affirm that whatever he has taught is from Allah. (It is of the principles of beliefs) to affirm and accept that there is prayer five times every day. (It is of the principles of beliefs) to pay Zakat (charity), to fast in the month of Ramadan and to perform Hajj of the House (of Allah). (It is of the principles of beliefs) to love those who love us (‘A’immah from the family of the Messenger of Allah), to disown our enemies and to become part of the group of the truthful ones. (All such issues are of principles and obligatory matters).’”

Sheikh Al-Kulayni:

Abu Ali al-Ash’ari has narrated from al-Hassan ibn Ali al-Kufi from ‘Abbas ibn ‘Amir from Aban ibn ‘Uthman from Fudayl ibn Yasar from abu Ja’far, recipient of divine supreme covenant, who has said the following:
“Abu Ja'far, recipient of divine supreme covenant, has said, ‘Islam is based on five principles. They are: Prayer, al-Zakat (charity) fasting, Hajj and al-Wilayah. The call to none of the other principles has been so emphatic as it has been to al-Wilayah. People accepted the other four but they left aside this [al-Wilayah].’”
