The ruling on evicting a tenant because of an evil in his home

Question:
Honorable Shaykh, I seek Allah’s forgiveness. What is your opinion regarding what the property owners say when I tell them to evict such-and-such a neighbor because he has a dog? They say that they rented it to him on an annual contract, and it is not permissible to evict him until the contract expires. Is this statement correct?

Answer:
This is forbidding evil; it is obligatory to forbid evil. As for evicting him or not evicting him, that is the responsibility of the court. Forbidding evil, however, is obligatory.
