The document explains the ten nullifiers of Islam according to Imam Muhammad bin Abdul Wahhab. The first nullifier discussed is shirk, or associating partners with Allah in acts of worship. Examples given include sacrificing animals to other than Allah, such as the jinn or graves. The second nullifier is placing intermediaries between oneself and Allah, such as calling on prophets or saints rather than directly calling on Allah alone. Committing any of these ten nullifiers invalidates one's Islam and faith.
