Salaam Jinn,
Satan is identified as a Jinn in 18:50
And [mention] when We said to the angels, "Prostrate to Adam," and they prostrated, except for Iblees. He was of the jinn and departed from the command of his Lord. Then will you take him and his descendants as allies other than Me while they are enemies to you? Wretched it is for the wrongdoers as an exchange.
Satan was not mentioned in 18:50 but 'Iblees'
If you use 'WAS' for 'KAANA' in 18:50 instead of 'BECAME', you may find difficulty in translating the following aayaats.
2:34
وإذ قلنا للملئكة اسجدوا لءادم فسجدوا إلا إبليس أبى واستكبر وكان من الكفرين2:34 And We said to the angels: Yield to Adam, so they yielded except for Satan, he refused and became arrogant,
and became of the rejecters.If you translate 'kaana' as 'was' then in 2:34 above it has to be translated as 'and was of the rejectors' that means there were already rejectors available.
2:97
قل من كان عدوا لجبريل فإنه نزله على قلبك بإذن الله مصدقا لما بين يديه وهدى وبشرى للمؤمنين2:97 Say:
Whoever become an enemy to Jibraeel, then know that he has sent it down into your heart with the permission of Allah, authenticating what is with him, and a guide and good news for the believers.
2:111
وقالوا لن يدخل الجنة إلا من كان هودا أو نصرى تلك أمانيهم قل هاتوا برهنكم إن كنتم صدقين2:111 And they said: None shall enter the Paradise except
those who become Hoodan or Nasaara; this is what they wish! Say: Bring forth your proof if you are truthful.
4:1
يأيها الناس اتقوا ربكم الذي خلقكم من نفس وحدة وخلق منها زوجها وبث منهما رجالا كثيرا ونساء واتقوا الله الذي تساءلون به والأرحام إن الله كان عليكم رقيبا4:1 O people, be aware of your Lord who has created you from one person and He created from it its mate and sent forth from it many men and many women; and be aware of Allah whom you ask about, and the relatives.
Allah became Watcher over you.'Kun', 'Yakoon' and 'Fayakoon' is all derivatives of 'Kaana' used in the following aayat.
3:47
قالت رب أنى يكون لي ولد ولم يمسسني بشر قال كذلك الله يخلق ما يشاء إذا قضى أمرا فإنما يقول له كن فيكون3:47 She said: My Lord, how can
there be a son for me when no human being has been with me? He said: It is thus that Allah creates what He wills, when He decrees a command, He merely says to it
Be, and
it becomes.We know from verses such as 66:6 that Angels do not disobey God, since they are literally unable to.
Sorry, I disagree, that is not referring to all Angels.
66:6
يأيها الذين ءامنوا قوا أنفسكم وأهليكم نارا وقودها الناس والحجارة عليها ملئكة غلاظ شداد لا يعصون الله ما أمرهم ويفعلون ما يؤمرون66:6 O you who believe, protect yourselves and your families from
a Fire whose fuel is people and stones.
Over which are angels stern and powerful who do not disobey Allah in what He commanded them; and they carry out what they are commanded to.
This is referring to only angels over the fire.
May Allah guide us all to His path
