I can see assumptions all over this one. a) Satan was a Jinn-e-Kamil. b) He was very near to God. These are totally wrong. If he would have attained the "Kamal" (Perfection), he would have not made the mistake of disobeying God's command. Does worship (a mere exercise) has anything to do with purification? Munafiqeen worship throughout their lives, Khawarij were famous for their abundance of prayers & fastings. Why God has allowed Prophets & Imams to guide us? Is it like giving an exam? Where are the examiner? Are there angels watching

Why we only need to follow A Mujtahid? Why not we follow many mujtahideen at the same time? Or why not we take opinions from many scholars & act on the one which looks good to us?

What about Al-ilah?

Perhaps you can explain to me the difference between "Taoubah" & "Toubatan Nasooha".

May Allah (سُبْحَانَهُ وَ تَعَالَى) grant us the toufeeq of "Toubatan Nasooha". ( تَوْبَةً نَصُوحًا)

Stoning to death itself is another ijtihad. He deemed mut'ah as zina.

Hadith of Sahih Muslim is quoted above Can you read his words: فَلَنْ أُوتَى بِرَجُلٍ نَكَحَ امْرَأَةً إِلَى أَجَلٍ إِلاَّ رَجَمْتُهُ بِالْحِجَارَةِ And any person would come to me with a marriage of appointed duration (Mut'a), I would stone him (to death). Both the texts are taken from your source i.e., https://muflihun.com/muslim/7/2801

فَلَنْ أُوتَى بِرَجُلٍ نَكَحَ امْرَأَةً إِلَى أَجَلٍ إِلاَّ رَجَمْتُهُ بِالْحِجَارَةِ ‏ And any person would come to me with a marriage of appointed duration (Mut'a), I would stone him (to death).

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، يُحَدِّثُ عَنْ أَبِي نَضْرَةَ، قَالَ كَانَ ابْنُ عَبَّاسٍ يَأْمُرُ بِالْمُتْعَةِ وَكَانَ ابْنُ الزُّبَيْرِ يَنْهَى عَنْهَا قَالَ فَذَكَرْتُ ذَلِكَ لِجَابِرِ بْنِ عَبْدِ اللَّهِ فَقَالَ عَلَى يَدَىَّ دَارَ الْحَدِيثُ تَمَتَّعْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم ‏.‏ فَلَمَّا قَامَ عُمَرُ قَالَ إِنَّ اللَّهَ كَانَ يُحِلُّ لِرَسُولِهِ مَا شَاءَ بِمَا شَاءَ وَإِنَّ الْقُرْآنَ قَدْ نَزَلَ مَنَازِلَهُ فَأَتِمُّوا الْحَجَّ وَالْعُمْ

Was he unaware of the verse of Quran (Surah al Maida verse 5) too?

So you need more. Now understand the link:

If this is not sufficient, here is another: Perhaps you need more, here we go: Do you want more?

I don't know why you are rejecting Umar's own testimony. Here are few ahadith: If you say ibn Abbas was not there in Khyber, here is another:

I have just edited my comment to add more material to it. I am expecting that you perhaps would like to edit your comment too.

I would like to add one more of his wrong ijtihid. Surah Talaq of the Quran stipulates that there is no such thing as an impromptu triple divorce at one instance, rather the recital must take place over tree periods (Al-Qur’an Surah 65, verse 1), yet Khalifa Umar ruled that his subjects could divorce their wives by uttering the divorce recital in triplicate on one occasion. Interestingly his ijtihad never stopped here, he did away with the need of witnesses altogether, he entitled a man to utter the divorce immediately, without the need for a time to reflect or summon witnesses.
