What is the meaning of supporting the mushrikin (those who associate partners with Allah) and assisting them against the Muslims, and that this is among the nullifiers of Islam?

Question:
Many questions have come in asking about the meaning of the statement of Shaykh Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him) regarding the eighth nullifier of Islam, which is supporting the mushrikin and assisting them against the Muslims. They ask for clarification of this.

Answer:
This is clear; it does not require a separate explanation. Supporting the mushrikin and assisting them against the Muslims is clear. If this is established, then so be it. But if the matter is ambiguous and there is no clear support or assistance for the mushrikin, we will not rush to apply this ruling to people until we verify what constitutes support and what constitutes assistance.
If it is established, then the ruling stands as it is. But if the support and assistance are not established and the matter is ambiguous, we do not rush in this matter. It is obligatory for the student of knowledge not to rush in these matters and issue rulings haphazardly until he verifies whether they apply or not.
