(Thus We have revealed it as a Lecture in Arabic) We have sent down Gabriel with the Qur'an to Muhammad (pbuh) in the Arabic usage, (and have displayed therein) and have exposited in the Qur'an (certain threats) i.e. threats and promises, (that peradventure they may keep from evil) that perhaps they may ward off disbelief, idolatry and indecencies (or that it may cause them to take heed) or obtain a reward if they believed; it is also said that this means: or obtain eminence through the profession of Allah's divine Oneness; it is also said that this means: or incur chastisement if they did not believe.
