Dune

We walked on the dune.

From the tall dune I could see over the whole island.

From the high dune, I could see the whole island.

From the high dune, I had a view of the whole island.

I found her footprints in the sand of the dune.

Building a protective structure in front of a cliff or dune temporarily stabilizes the seaward location of the cliff or dune edge, however beach erosion continues. Since no new beach area is created through cliff or dune retreat, a net loss of beach area occurs.

High wind can cause a sand dune to swallow up a young child unexpectedly.

Since my teenage years, I have enjoyed the Dune franchise of Frank Herbert—the literature and movies. The setting is many thousands of years into the future, as humankind has expanded throughout the galaxy. The official language of the Imperium is called Galach, a descendant of Earth's English, Russian, and other languages. Meanwhile, on the desert planet Arrakis, the Fremen eke a living as desert people. The Fremen language is a descendant of Earth's Arabic.

Like Christianity and Judaism, Islam is a so-called Abrahamic religion. Muslims, as Islamic people are called, repudiate Christianity's Trinity which alludes to polytheism. Islam is strictly monotheistic as they believe that there is only One God, Allāh. Their sacred writings are in the Qur'an, divided into 114 suras, containing 6236 āyāt, verses. Muslims believe that the Qur'an is only perfect in the original Arabic because any translation would be deficient. Their main prophet is Muhammad, the messenger. Muslim eschatology includes bodily resurrection at the Day of Resurrection, Yawm al-Qiyāmah, when everyone will be judged for good or bad deeds. Trials and tribulation precede and coincide with al-Qiyāmah, the time of which no human knows. (I read somewhere too that in Islam, being in hell may be an impermanent condition.) Like other Abrahamicists, Muslims believe in angels. Muslims believe in predestination or divine preordainment. Muslims must pray 5 times during the day. The prayer rituals are called Ṣalāh. Like other religions, Islam has subdivisions, as the Sunni and Shia, the contention being the successor, Abu Bakr or Ali respectively, to Muhammad. (The Islamic religion's progression and overall ambiance are depicted in Frank Herbert's Dune series, which is set thousands of years from now in outer space. There is a desert planet called Arrakis.)
