I have continued the other deck for Arabic on Duolingo and will keep adding cards. There is no audio.
Full diacritics (short vowels, doubling of consonants, ...) is provided, except:
ال, which makes a word definite is usually written without the َ , so it's المَلِك in stead of أَلْمَلِك.
when a consonant without diacritic is followed by ا ، ي، و these are used as long vowels. Eg. ري is pronounced rii, but رَي is pronounced as ray.
the words are written in the pausal form, not the nominative. Eg. ملك، الملك, in stead of مَلِكٌ، المَلِكُ.

At this time, it is not possible to add shared decks directly to your
AnkiWeb account - they need to be added from the desktop then synchronized
to AnkiWeb.
