Surah 12. Yusuf, Ayah 2

This, according to Zamakhshari, is the meaning of la'allakum ta'qilun in the above context. Although they were in the first instance addressed to the Arabian contemporaries of the Prophet, these two verses apply to all people, whatever their origin, who understand the Arabic language. They are meant to impress upon everyone who listens to or reads the Qur'an that its appeal is directed, primarily, to man's reason, and that "feeling" alone can never provide a sufficient basis of faith. (See also 13:37 and 14:4 , as well as the corresponding notes.)

 Quran literally means recitation.

 The address here is to the Arabs and, by extension, all of humanity.

Qur-an means: something (1) to be read, or (2) recited, or (3) proclaimed. It may apply to a verse, or a Sura, or to the whole Book of Revelation.
