The Virtue of the Qur'an Here

Allah points out the noble status of the Qur'an and urges them to recognize its worth:

﴿ لَقَدۡ أَنزَلۡنَآ إِلَيۡكُمۡ ڪِتَـٰبً۬ا فِيهِ ذِكۡرُكُمۡ‌ۖ ﴾

(Indeed, We have sent down for you a Book in which there is Dhikrukum). Ibn `Abbas said: "Honor for you.''

﴿ أَفَلَا تَعۡقِلُونَ ﴾

(Will you not then understand) means, will you not understand this blessing, and accept it This is like the Ayah:

﴿ وَإِنَّهُ ۥ لَذِكۡرٌ۬ لَّكَ وَلِقَوۡمِكَ‌ۖ وَسَوۡفَ تُسۡـَٔلُونَ ﴾

(And verily, this is indeed a Reminder for you and your people, and you will be questioned.) (43:44)
