I just realised recently that the Quran in Madinah hafs has changed.
The fonts changed. Thus the placement of some ayat r not the same as the old ones.
For visual peeps who memorised the Quran, they can detect it easy.
I used to be visual. I memorised the placement/location of the Sura (right or left of page) and the location of the sentences (I remembered Al-A'laq is complete in 1 page for old ones whereas the new ones, some continued in another page. I remembered cos of The sujud tilawah/prostration symbol).
For many decades, all haj pilgrims got a free Mushaf Quran. And it has been the same only in my recent Umrah, I noticed the changes.
And I used the new Quran, recently unknowingly n I felt that my visualed memory of past hifz was a bit off.
Me n my kids - we have memorised using the Old Quran. Thus to change is challenging. We r often advised to use only 1 same type.
Anyway, it's no biggie for some.
The words r still the same. The meaning too. Just the visual of it...
But just FYI...
Most of the Quran printed or sold in Singapore, Malaysia, Indonesia are based on the old Quran especially those huge A4 with tafsir.
Again, I remind that nothing has changed. Quran years ago till now, only the type of fonts used r different. Perhaps also inclusion of symbols like dhommah, kasrah, fathah, sukun n more for non Arabs to learn to read easy...
(also Quran in India (Baghdadi Quran?) may looked different but it's the same-as compared with Saudi ones - again the font n symbols may looked different.
No worries, if u can read the Quran, u can read any Quran regardless where it is manufactured.
