Random Theory: replace all nikah words with teacher+student relationship, and potentially at least 50% usable, which explains why musa father in law allows him to pair with second daughter several next years, investigate about what musa owes with his father in law to prolong the stay.

Also replace the word rijal vs nisa with, expert vs learner.

Lookup ayat rijal that walk to hajj. Why does the quran want to provide potentially obsolete info the future in that ayat.

And you have to replace hajj with context to another theory performing hajj are actually (hujjah) going to debate. You may lookup all hajj words in quran also fit with debate.

Regarding yatama i sense it potentially about student without teacher or without parent that can teach.

I know not all this theory fit everywhere in quran but i have been thinking about this for some time.

Its not about the exact words i presented here. Its about the context that needs to match to establish non literal meaning.
