Surah 54. Al-Qamar, Ayah 17

The noun dhikr primarily denotes "remembrance", or - as defined by Raghib - the "presence [of something] in the mind". Conceptually, and as used in the above context as well as in verses {22}, {32} and {40}, this term comprises the twin notions of understanding and remembering, i.e., bearing something in mind.

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?
