When we teach Quran to kids, we always put hamza with Alif.
أَ. أرايت
أُ - أحي
أْ - سبأ
إِ - إهدنا
and usually when it is a silent sound we just put alif without Hamza ا - رينا لا تآخذنا إن نسينا أو اخطأنا
Go to the back of the mushaf and you will find rules of reading Quran. In regular academic Arabic, you shouldn’t encounter this issue at all.
