Оттуда же и Иблис:

Ибли́с (араб. إبليس‎) — в исламе: имя джинна, который благодаря своему усердию достиг того, что был приближен Богом, и пребывал среди ангелов, но из-за своей гордыни был низвергнут с небес. После своего низвержения Иблис стал врагом Аллаха и людей, сбивая верующих с верного пути.

Вот обратите внимание:

evil (adj.) Look up evil at Dictionary.com
Old English yfel (Kentish evel) "bad, vicious, ill, wicked," from Proto-Germanic *ubilaz (source also of Old Saxon ubil, Old Frisian and Middle Dutch evel, Dutch euvel, Old High German ubil, German übel, Gothic ubils), from PIE *upelo-, from root *wap- "bad, evil" (source also of Hittite huwapp- "evil").

In Old English and other older Germanic languages other than Scandinavian, "this word is the most comprehensive adjectival expression of disapproval, dislike or disparagement" . Evil was the word the Anglo-Saxons used where we would use bad, cruel, unskillful, defective (adj.), or harm (n.), crime, misfortune, disease (n.). In Middle English, bad took the wider range of senses and evil began to focus on moral badness. Both words have good as their opposite. Evil-favored (1520s) meant "ugly." Evilchild is attested as an English surname from 13c.

The adverb is Old English yfele, originally of words or speech. Also as a noun in Old English, "what is bad; sin, wickedness; anything that causes injury, morally or physically." Especially of a malady or disease from c. 1200. The meaning "extreme moral wickedness" was one of the senses of the Old English noun, but it did not become established as the main sense of the modern word until 18c . As a noun, Middle English also had evilty. Related: Evilly. Evil eye (Latin oculus malus) was Old English eage yfel. The jocular notion of an evil twin as an excuse for regrettable deeds is by 1986, American English, from an old motif in mythology.

Не удивлюсь, если узнаю, что до конца 18 века в английском языке это самое evil было напрямую привязано к дьяволу.

А вот понятие добра, оказывается, раньше оно звучало не как "good", а как "god" и было напрямую связано с Господом:

good (adj.) Look up good at Dictionary.com
Old English god (with a long "o") "excellent, fine; valuable; desirable, favorable, beneficial; full, entire, complete;" of abstractions, actions, etc., "beneficial, effective; righteous, pious;" of persons or souls, "righteous, pious, virtuous;" probably originally "having the right or desirable quality," from Proto-Germanic *godaz "fitting, suitable" (source also of Old Norse goðr, Dutch goed, Old High German guot, German gut, Gothic goþs), originally "fit, adequate, belonging together," from PIE root *ghedh- "to unite, be associated, suitable" (source also of Old Church Slavonic godu "pleasing time," Russian godnyi "fit, suitable," Old English gædrian "to gather, to take up together").

Irregular comparative and superlative (better, best) reflect a widespread pattern in words for "good," as in Latin bonus, melior, optimus.

Sense of "kind, benevolent" is from late Old English in reference to persons or God , from mid-14c. of actions. That of "friendly, gracious" is from c. 1200. Meaning "fortunate, prosperous, favorable" was in late Old English. As an expression of satisfaction, from early 15c. Of persons, "skilled (at a profession or occupation), expert," in late Old English, now typically with at; in Middle English with of or to. Of children, "well-behaved," by 1690s. Of money, "not debased, standard as to value," from late 14c. From c. 1200 of numbers or quantities, "large, great," of time or distance, "long;" good while "a considerable time" is from c. 1300; good way "a great distance" is mid-15c.
Why then, can one desire too much of a good thing. <"As You Like It">
As good as "practically, virtually" is from mid-14c.; to be good for "beneficial to" is from late 14c. To make good "repay (costs, expenses), atone for (a sin or an offense)" is from late 14c. To have a good mind "have an earnest desire" (to do something) is from c. 1500. Good deed, good works were in Old English as "an act of piety;" good deed specifically as "act of service to others" was reinforced early 20c. by Boy Scouting. Good turn is from c. 1400. Good sport, of persons, is from 1906. The good book "the Bible" attested from 1801, originally in missionary literature describing the language of conversion efforts in American Indian tribes. Good to go is attested from 1989.

"good book" - это, оказывается, не "хорошая книга", как сейчас, а просто "книга Господа", Библия..

И еще оказывается, что слово "god"-Господь раньше существовало и в немецком,норвежском, голландском языках.
