Moses: But we do believe in many prophets of whom we read of no miracles, such as Jeremias, Abdias, Amos, Osee and others. Peter: Miracles are not to be sought in their case, because they did not introduce any novelty of law . The Latins agreed with the first Quraysh against whose unbelief the Qur’anic revelations about miracles were directed. — Norman Daniel, Islam and the West, 422
