Looks OK to me - @khaledhosny WDYT?

The vowel marks in Noto Naskh Arabic are indeed to small to the point of being unusable at text font sizes. So making them larger is an improvement.

Looking at the updated sources, other marks that use the adjusted ones as components need to be fixed:
fathaDotabove-ar
kasraDotbelow-ar
dammaDot-ar

Many other vowel marks need to be adjusted as well to maintain consistency, for example (may be more):
fathaHorizont-ar
fathatwodots-ar
fathaRing-ar
noonghunnaabove-ar
noonghunnaabovesideways-ar
toneloopabove-ar
leftarrowheadabove-ar
rightarrowheadabove-ar
doublerightarrowheadabove-ar
doublerightarrowheadDotabove-ar
rightarrowheadDotabove-ar
toneonedotabove-ar
tonetwodotsabove-ar
sukunoval-ar
sukunround-ar
jazm-ar
rhombusStopabove-ar
toneloopbelow-ar
leftarrowheadbelow-ar
rightarrowheadbelow-ar
toneonedotbelow-ar
tonetwodotsbelow-ar
rhombusStopbelow-ar

Interestingly, I noticed a few days ago that the original Droid Arabic Naskh had larger vowel marks, so it would be interesting to know why they were made much smaller in Noto Naskh Arabic.

Droid above, Noto from main branch below (the overall size is also smaller, I had to use 14pt for Noto to get the same size as 12pt Droid):

@simoncozens @khaledhosny

Thank you for reviewing this pull request. I have adjusted the three components pointed out by @khaledhosny and would appreciate your confirmation.

I'm also grateful for highlighting the vowel marks that may need adjustment to maintain consistency with the components modified in this pull request. Upon examining some of the vowel marks @khaledhosny mentioned, it appears that some were originally large and may not require adjustment. For example, vowel marks like doublerightarrowheadabove-ar and doublerightarrowheadDotabove-ar seem larger than Sukun and Fatha.

Considering these points, I would like to inquire about your opinion on whether this pull request can be merged at this time. Or, would you prefer that I review the vowel marks @khaledhosny mentioned, make any necessary adjustments, and submit a new pull request?

I would appreciate your feedback on this matter.
