Translation:

17. And We have indeed made the Qur'an easy to understand and remember: then is there any that will receive admonition?

Notes (Tafseer)

5143. While the Qur-an sums up the highest philosophy of the inner life, its simple directions for conduct are plain and easy to understand and act upon. Is this not in itself a part of the Grace of Allah? And what excuse is there for any one to fail in receiving admonition?
