I consider this wrong input so it is not supported by Amiri; the Hamza
in بءايت is exactly the same Hamza in ءايت prefixed with ب, so the same
Unicode character should be used in both, and Amiri goes to a great
length to support this. Using a combing Hamza (which is a different
Hamza) over a Tatweel is just a hack to emulate the same effect that you
get “natively” with Amiri, I may support it in the future, but it is not
a priority. If you read Arabic, the Amiri manual describes the proper
Unicode sequences to input some of the Quranic marks that people get
confused about because of the messiness of this area in Unicode (I
should translate the manual to English, but time is always an issue).

This seems like a font hack, the proper way to input the Aya mark is
what Ondřej describes in his reply.
