Questions on the Explanation of the Book of Nullifiers of Islam

Question:
Is it obligatory to declare as a disbeliever (takfir) one who hates something from the Book of Allah or the Sunnah of His Prophet (peace and blessings be upon him), and this hatred is apparent?

Answer:
If he displays the hatred and says, "I hate, I hate what came from Allah and from His Messenger," there is no doubt in his disbelief (kufr). But if he does not express this, and it is only in his heart, then no one knows it except Allah (Mighty and Majestic). However, if he speaks and says, "I hate this hadith," or "I dislike this verse," or something similar, he has explicitly declared disbelief, and may Allah protect us from that. He is judged by what his tongue utters. But if he does not speak, we have only the outward appearance to go by, and no one knows what is in the hearts except Allah (Mighty and Majestic).
