But sometimes we do it nevertheless.
Somewhere I had read that in India the Kufī numbering system
has five more verses than the Egyptian Kufī system ‒
without moving any end of verse (therefore both being Kufī),
just by splitting five long verses.
Adrian Alan Brockett wrote that in the 20th century the differences have been reduced
‒ without giving chapter and verse.
But here are four places where India used to differ from Arabia:
4:173, 6:73, 36:34+5 were
4:173+4 , 6:73+4 resp. 36:34.
In Encyclopedia of Islam II A.T.Welch writes that in India 18:18 was split in two. I can not confirm this. He further writes that Pickthall has this split verse ‒ correct ‒, and that it was only changed in 1976 ‒ it was changed in 1938.BTW, the Ottomans did not have here an additional end of verse:
added later:
2:246 and 41:45 can be different in India from Gizeh24 (Brockett p.29)
BHO had both Kufī and Baṣrī, known 100% like "modern" Kufī.
HOQz, MNQ, (HaRi and ar-Rušdi) had exactly the same Kufī numbers as we have today ‒ like Muṣḥaf al-Muḫallalātī and KFE.
al-Muḫallalātī is even one of the four authorities giving in Hyderabad38:
