Iblis

Iblīs (literally: dispraiser, plural abālisa(h) or abālīs, feminine iblīsa(h) and also known as Satan or Devil) is the highest rank of demons and devils in Islam. Also used as epithet for both al-Ḥāriṯ and Samael, Judeo-Christian Satan and Lucifer, Yazidi Peacock Angel, and Sufi Marra.

Should not to be confused with marids who are just highest ranks in fiction.

Those abālīs are related to tawaghit (an evil jinn, devils, or fallen angels who posing as gods).

Some said the name of Azazil (al-Ḥāriṯ) changed to Iblīs that's wrong because the names of disbelievers never mentioned in the Quran and the name Azazil only mentioned in the Tafsirs and Judaeo-Christian sources, the reason why words like إبليس "Iblīs" or فرعون "Firʿawn; the Pharaoh" never definitised by ال "al" or mentioned by plural form because they referred to one character and the titles only definitised if the name mentioned or with well known characters (with names and every detail, and unlike the Sunnah there is no much detail in the Quranic stories: then the only character mentioned by detail is the prophet Yusuf "Joseph")

Etymology
The word Iblīs came from either the Semitic root B-L-S "Have no goodness, accursed, despaired from God's mercy, person who cause confusion" linked to the root l-b-s "related to clothes, covers, or equipment and confusion" (Iblīs can also means the person whom covers the truth and mix it with the injustice), Ancient Greek Diabolos (accuser and slanderer, demon, or Satan) related to Arabic root š-t-n (related to torch and burning) Also related to Ge'ez root ś-t-n and Hebrew root s-t-n (Satan, Devil, or problem-maker) or from both Arabic and Greek roots, Both Greek and Arabic roots able to base the meaning Devil or Satan from them.
