الم تعلم ان الله يعلم ما في السماء والارض ان ذلك في كتاب ان ذلك على الله يسير

أَلَمْ تَعْلَمْ أَنَّ ٱللَّهَ يَعْلَمُ مَا فِى ٱلسَّمَآءِ وَٱلْأَرْضِ ۗ إِنَّ ذَٰلِكَ فِى كِتَـٰبٍ ۚ إِنَّ ذَٰلِكَ عَلَى ٱللَّهِ يَسِيرٌ

Surat Al-Haj is named after an event of rites which these verses emphasize. We're also reconnected to our history of previous nations and their rites they were commanded to perform (such as prophet Abrahim AS who was a nation on his own). The concept of knowledge as also reintroduced as Allah brings up the Book, not necessarily the Quran. We're reminded of Allah's distaste for those who dispute without knowledge. #SuratAlHaj

But if they argue with you, then say, “Allah knows best what you do.”

Allah will judge between you ˹all˺ on Judgment Day regarding your differences.

Do you not know that Allah ˹fully˺ knows whatever is in the heavens and the earth? Surely it is all ˹written˺ in a Record. That is certainly easy for Allah.

Yet they worship besides Allah that for which He has sent down no authority, and of which they have no knowledge. The wrongdoers will have no helper.

Hana Alasry's Reflection on Surah Al-Hajj:68 - 71

In verse 1, put simply, God did not come to play. Allah sets the scene for very serious warnings. Allah uses the world "zalzalat" in reference to the Day of Judgement, and while it refers to the physical quaking/shaking of the Earth, we can understand it as so awe-strikingly terrifying that it "shakes" each creation of Allah; human, jinn, animals, and even mountains.
In the second verse, Allah describes events we find incredibly off-putting in the dunya. We frown upon the drunkard in the street and we could not even imagine our disgust at the mother who leaves her child in harm's way willingly and we are grief-stricken by the thought of a woman miscarrying. The severity of these events, again reflect the severity of the events of the Day of Judgement. I often find myself saying that the best time to understand the true nature of someone is in the extreme circumstances (usually stress). That's when the nature of the heart shows (is the person truly patient? Merciful? Steadfast? etc). In the extreme stress of that Day, the true nature of mankind will show. That true nature is one of khashya (awe-inspiring fear) of Allah, one of undenounced belief in the One Lord and in His qualities that are neither restricted or bound by any physical law. 
The miscarriage portion is interesting in that we understand physiologically that extreme emotional stress can result in spontaneous abortion. But interesting to note is that, at that point, there is no more earth for that possible child to dwell in the first place. #DayofJudgement  #SuratAlHaj 

O humanity! Fear your Lord, for the ˹violent˺ quaking at the Hour is surely a dreadful thing.

The Day you see it, every nursing mother will abandon what she is nursing, and every pregnant woman will deliver her burden ˹prematurely˺. And you will see people ˹as if they were˺ drunk, though they will not be drunk; but the torment of Allah is ˹terribly˺ severe.

Hana Alasry's Reflection on Surah Al-Hajj:1 - 2

One of the first things we learn about are the stories of Prophets. And one of the first things we forget about as we grow in our knowledge of the complexities of Islam are... the stories of the prophets (may Allah's blessing be on them). It's very interesting because they are a wrought reminder to us of the very patterns of self-destruction that exist today. From heedlessness to arrogance to sticking to the status quo because it was "what our forefathers left us" aka "all we've ever known." I'm reminded of the understanding that Allah does not destroy a nation unless it is unjust/oppressive, whether a Muslim nation or Kaffir nation. #SuratAlHaj

If they deny you ˹O Prophet˺, so did the people of Noah before them, as well as ˹the tribes of˺ ’Ȃd and Thamûd,

the people of Abraham, the people of Lot,

and the residents of Midian. And Moses was denied ˹too˺. But I delayed ˹the fate of˺ the disbelievers ˹until their appointed time˺ then seized them. And how severe was My response!

Many are the societies We have destroyed for persisting in wrongdoing, leaving them in total ruin. ˹Many are˺ also the abandoned wells and lofty palaces!

Have they not travelled throughout the land so their hearts may reason, and their ears may listen? Indeed, it is not the eyes that are blind, but it is the hearts in the chests that grow blind.

They challenge you ˹O Prophet˺ to hasten the torment. And Allah will never fail in His promise. But a day with your Lord is indeed like a thousand years by your counting.

Hana Alasry's Reflection on Surah Al-Hajj:42 - 47

The main purpose of Hajj is to ‘remember Allah’

-10 days of dul-Hijjah, Allah says: 

   “That they may witness benefits for themselves and mention the name of Allah on known days…..”[hajj:28]

-in Muzdalifa, Allah says:

 “But when you depart from 'Arafat, remember Allah at al- Mash'ar al-Haram. And remember Him, as He has guided you, for indeed, you were before that among those astray.[Al-Baqara:198]

-days of Tashreeq , Allah says : 

“And remember Allah during [specific] numbered days. …[Al-Baqara:203]

-when slaughtering Qurbani

“ And for all religion We have appointed a rite [of sacrifice] that they may “mention the name of Allah “”over what He has provided for them of [sacrificial] animals. ”[Al-Hajj:34]

“  Their meat will not reach Allah, nor will their blood, but what reaches Him is piety from you. Thus have We subjected them to you that you may glorify Allah for that [to] which He has guided you; and give good tidings to the doers of good.”[Al-Hajj:37]

- End of Hajj, Allah says:

“ So when you have accomplished your Manasik [(i.e. Ihram, Tawaf of the Ka'bah and As-Safa and Al-Marwah), stay at 'Arafat, Muzdalifah and Mina, Ramy of Jamarat, (stoning of the specified pillars in Mina) slaughtering of Hady (animal, etc.)]. “”Remember Allah as you remember your forefathers or with a far more remembrance.” “[Al-Baqara:200]
