“Aya” is Arabic for evidence, proof or miracle. Each paragraph in the Quran is also referred to as Aya.
Though the name of the project here comes from South African Fern
I heard that term, but as "Ayat". Which one is correct?
Ayat is the plural of Aya.
Aya is also what you start yes-no questions with in Farsi. Cool to see something similar, like you're asking for evidence, "prove that you are going" means "are you going?".
