In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Al-Allamah Salih Al-Fawzan, may Allah preserve him, was asked:

Is it correct that the first to innovate the path of the Raafidah was Abdullah Ibn Saba – a Yahudi?

Response:

Yes, without a doubt. The Rafidah or the Shiites in general are of two types: The Shiites from the fire worshipers and the Shiites from the Yahud. They hide behind Islam to corrupt it. The Yahud plotted through Abdullah Ibn Sabah and the first thing he began with was to ignite fitnah against Uthman, may Allah be pleased with him. Listen below:

Al-Allamah Rabee Bin Hadi Al-Madkhali, may Allah have mercy upon him, was asked:

Our Shaikh, may Allah preserve you. The questioner says: What is the ruling on the common people of the Rawafid and how do we deal with them?

Answer:

The questioner differentiates between the common people and other than them. This is a good approach. The common people who neither speak ill of the wives of Allah’s Messenger, peace and blessings of Allah be upon him, nor do they declare the companions to be disbelievers, nor do they believe that the Qur’an is distorted; however, they have some Rafd [i.e. beliefs of the rafidah] and some hatred for the companions without declaring them disbelievers and what is similar to (these deeds), these ones are misguided innovators in religious matters and we do not declare them disbelievers. (But) whoever joins their heretics in declaring the companions of Muhammad, peace and blessings of Allah be upon him, to be disbelievers, speaking ill of the wives of Allah’s Messenger, and the filthy belief that the Qur’an has been distorted, and that there is an addition and deficiency in it, this (person) is a disbeliever similar to the disbelievers of the Yahud and Nasara. There is no distinction between their common people and their scholars (in this affair).

Question: How do we deal with them?

Answer: If dealing with them is with regards to a worldly affair—business transactions and what is similar to that— it is permissible to trade with a Yahudi, a Nasrani and a Rafidi. However, as for co-operating with them in issues of religion, no.

وَلَا تَعَاوَنُواْ عَلَى ٱلۡإِثۡمِ وَٱلۡعُدۡوَٲنِ‌ۚ

Do not help one another in sin and transgression. [5:2]

Rather their scholars and callers are boycotted and they are warned against.
