Here are the grammatical errors and issues in the text you provided:
-
"Wahhabism is a religion known for its strict interpretation of Islam and the importance in following the teachings of Muhammad."
- Error: The phrase "the importance in following" should be more clearly stated. It would be more accurate to say "the importance of following" to indicate the correct relationship.
-
"Wahhabism has the most influence Saudi Arabia."
- Error: A preposition is missing before "Saudi Arabia." It should read "Wahhabism has the most influence in Saudi Arabia."
-
"It has a big influence on the country's laws."
- While not strictly a grammatical error, the phrase "big influence" could be replaced with "significant influence" for a more formal tone. However, this isn't necessary for correctness.
Here is a summary of the identified errors:
- "the importance in following" should be "the importance of following."
- Missing preposition: "in Saudi Arabia" needed in the second sentence.
Thank you!
