Its seen as a sunnathillah (way of Allah ) to provide in abundance any most essential thing for the humans like air followed by waterfood, iron, wood etc etc . Similarly in the glorious Quran Allah Ar Rahmaan Al Wadood repeats them (mostly) as per its importance like the most repeated Order of Allah is about Tawheed and rejection of Shirk , followed by salah & zakat etc and similarly among WARNING Allah, Al wadood repeats and warns about the enemy of our parents & us thats ' Iblis laanathullah '' in more than 90 verses and this incident of his refusal of prostration is in atleast seven different suras which made me to keep thinking a little deeper on this subject.
Though Allahuaalam it all happened as per the decree of Allah but the reasons behind any mishap or tragedy ( like iblis falling from the top as a head & teacher of Angels after worshiping Allah for more than a 1000 milleniums to the lowest of the lows-than a cockroach ) needs to pondered and remembered for us for protecting ourselves from falling into this sad qadr of MISFORTUNE or bad naseeb ( badhnaseeb in Urdu) .
imho the first mistake of iblis is leaving Islam (submission willfully to the will of Allah our Rab our Creator ) that he was not happy when Allah created a khalifa for this Earth ( though angels did ask
Allah ar Rahmaan about it but only with doubt
) but Iblis persisted more further with his thakkabur (arrogance) & jealousy (the two DANGEROUS hidden SINS after kufr & shirk ) that consequently lead Iblis , Azazil, into the Biggest sin of Kufr itself
. But its to be noted that by then still Iblis addresses Allah as My lord but its seen any mistakes by those in high position near Allah are treated as big mistakes (as incase of small mistake of Yunus AS of emigrating without Allah's order he was put into a whales' stomach ) because Allah expects the highest character from those who have become near to Allah.
The Question could be, why Allah created a commotion by ordering his dearest All Angels and their leader (iblis) to prostrate to Adam AS ?
The answer is Allahu aalam but may our Rab forgive us on speculating on this . Nothing is hidden to Allah about any of his Creations even about a leaf about to fall (The Noble Quran) or about the thinking of angels or their leader, Teacher Iblis or adam, Allah knows what was all in their hearts and Allah had made paradise free of sinners as per his Law.
So jealousy & thakkabur (though it was only in iblisis's heart )
was not acceptable to Allah in Paradise as per the hadith something like None will enter Jannah or paradise with an Atom of thakkabur, arrogance '
' its sunathillah that Allah puts in trails & tests as an expatiation of sin or to raise some one's status in his position new it close to Allah. for more regular and grave sinners Allah puts them in trials and tests making them further DEEP into their sins and misfortune as was for firaun etc giving them more power and wealth.
So When Iblis started to feel jealous about Adam and felt himself he was more pure and holy (like Mufti Menk said) imho Allah knew it immediately and that was a SIN ( a big sin for the status of the Leader of pure Angels) and the trial was the balaah or bad omen of his sin of jealousy and thakkabur of being pure and holy ( ie forgetting Allah's favour on him that has kept him pure , holy ie iow lahaula laaquwatta illah billah ...) no wonder Prophet :saws: had mentioned none enter Paradise WITHOUT THE MERCY OF ALLAH even for himself
So Allah put him to test of doing something which was against his ego
, to prostrate to Adam whom he despised where he could not give up his urge of nafs So its very important to people of thakwa to fear and consider even their small mistakes as big ( to continue to be on the right path)because that's the trait of a Muhmin. But iblis's mistake was a Big Mistake as he rejected Allah Rabbul aalameen's direct order to prostrate to Adam and thus became a rejector or a kaffir.
But Imho as Allah is the Al Ghafoor, if iblis had realised his mistake and repented to Allah al Ghafoor Allahu aalam, Allah would have forgiven him because Allah loves those most who are pious and close to him like Prophet Adam whose mistake was a VVVERY BIG mistake since he doubted Allah (after even seeing Allah) on the well wishing of Allah
( no one could wish more good for us more than Allah al wadood, he cares for us more than we could care for ourselves or our Mother, just think , who fed us & cared us while we were in the womb of our mother ? ) and went to beleive Iblis - satan instead
who whispered to him that by eating the forbidden fruit he will leave for eternity and did kufr as well but still Allah al Wadood forgave him after his taubatun nasuha or SINCERE repentance Allah raised Adam AS again to live in the first heaven as per now in comfort though he laughs and cries on seeing his bad & good progeny of souls on the lowest sky.
POINTS TO REMEMBER
1) The pious people are to be VERY CAREFUL even from small sins since it could be a big sin for your CALIBRE
2)To Accept islam COMPLETELY and accepting al qadr of Allah willingly even though Allah has put you in the severest of tests and submit to him completely
3) An atom of thakabbur can stop you from entering jannah so VIGILANTLY avoid it since its a hidden sin in the heart which Allah knows as in case of iblis.
4) avoid jealousy since its Allah the creator decides to give what to whom
5) these two big sins will lead to kufur and also suspicion since it could be iblis suspicion that Adam will take over him6) If you have Sinned, turn to Al ghafoor and do taubatun nasuha , sincere repentance in real sense since Allah is most happy for his good slaves turn back to him after their inevitable sin and he wants to forgive them fullfilling his kindest attribute of Al ghafoor Al Wadood etc
Note : May allah forgive me , if this post had exceeded some where some how the knowledgeable are requested to correct them with daleel, jazakallah khairMa.
May Allah give the sayer first to follow what he has said ameen.
as to the question of the OP my view is Allah does as his attributes describe about him so Allah showed he is
The reckoner '' as per his attribute is
for Iblis 's Mistakes
though it was hidden to Angels and even to humans as per this verse http://legacy.quran.com/2/284
'' To Allah belongs all that is in the heavens and all that is on the earth, and whether you disclose what is in your ownselves or conceal it
, Allah will call you to account for it.
Then He forgives whom He wills and punishes whom He wills
. And Allah is Able to do all things.''
