One of those English words which have mystic origins traced back to Arabic.

In online English Etymology Dictionary INSTANT is explained as below:
late 14c., “infinitely short space of time,” from O.Fr. instant (adj.) “assiduous, at hand,” from M.L. instantem (nom. instans), from L. instantem “present, pressing, urgent,” prp. of instare “to urge, to stand near, be present (to urge one’s case),” from in- “in” + stare “to stand,” from PIE base *sta- “to stand” (see stet). Elliptical use of the O.Fr. adj. as a noun.

What is mentioned in the dictionary is right but there are more knowledge in this word. I will try to use Arabic to explain some knowledge within this word.
INS-AN: is an Arabic term used in the Qur’AN to refer to HUM-AN in English. Although Hu-M-AN is its self is another non-English word being used by people without understanding deep meanings beyond it.
Just as SAT-AN coming from Arabic SHAY-T-AN.
“INS” in Arabic means “Pupil”.
When we add suffix “TAN” to it it becomes A Pupil in “AN”. Suffix “AN” in Arabic makes a thing Double or Dual or TWO.
INS-TANT is a pupil seeing in “AN”. Or “AN” makes it “Two pupils”. What was “AN” then?

“ÂN” is a part of the sacred command KûN. ‘Kûn’ means ‘Be’ in English.Everything is created in “ÂN” with that sacred commANd of ALLAH. ÂN is Impartible Indivisible Particle of Time(ZamÂn). The seed of Time in Sha’anullah, which is perceived as Time in this world of testimony(‘alam al-shahada). “ÂN” is the Essence and Reality of Time. Time is a Tool but Aim is to reach “ÂN”.
Time is a perception and conjecture of “ÂN”s by our minds. That conjecture is called ‘zANn’. Time is called ZamAN in Turkish. Zam means ‘rise or increase’. So increasing AN’s are perceived as Time (ZamAN ) by our minds. At every “ÂN”, everything becomes non-existent and re-created again. But the mind perceives this as continual, in fact everything goes and comes, on and off in every “ÂN”. That is why the ones who watch this in the screen of their minds are always in conjecture(zANn). Allah knows best…

In the mind of human being,
an event(Olay) is born from the relation of two things,
time(ZamÂn) is born from the relation of two events, and
conjecture(ZaNN) is born from the relation of two times and know that this is the basis of the Servanthood Test…

“Wa in tuti’aksara men fi al’ardi yudilluka an sabilillah iy yattabiuna illaz zANna wa in hum illa yakhrusuna: Wert thou to follow the common run of those on earth, they will lead thee from the way of Allah. They follow nothing but conjecture: they do nothing but lie “ Qur’an [6/116]

Now I hope this explanation was enought to see what INSTANT meant for the ones who can think of!…

Origin of the word “SATAN” used in the Christianity is Arabic Term “SHAYTAN” used in Qur’AN by ALLAH j.j. When you look at the meaning of this word in English Resources, one will not find much things. But When you look in to Arabic origin, you will learn
SHAY: means THING(singular)
SHAY-TAN: Two THINGS.
SHAYTAN means the one who causes DUALITY. SEEING through dual vision in “AN” or in every INSTANT!…
We are explaining this knowledge to people so that some may have other meanings in the Qur’an when they read. We are neither eytmology experts nor a language analyser so we are not claiming anything. We are just saying that we see these in this way inshaallah.
