The Qur'an describes itself as a guidance from Allah that is without doubt. It was sent down as truth and to be a criterion to distinguish right from wrong. The Qur'an confirms the revelations that came before it and warns people of Makkah and those around it. Muslims believe in the Qur'an and guard their prayers. It was brought as a book explained in detail with knowledge, as guidance and mercy for believers. When the Qur'an's verses are recited, listen and be silent to receive mercy. The Qur'an contains miracles that only Allah knows the meanings of.
