What does Aariz mean?
In its Quranic sense (Quran 46:24) 'arid (عارض) denotes a cloud appearing on the horizon that is expected to bring rain, so Aariz is often glossed 'rain-bearing cloud'. Popular South Asian usage also gives 'respectable' or 'intelligent', which are not well documented in classical Arabic, so the meaning is hedged. Spellings include Aariz, Aaraiz, Ariz.
What does Hadi mean?
From the root h-d-y (ه-د-ي, 'to guide, to lead rightly'), meaning 'guide, leader, one who directs to the right path'. Al-Hadi is also one of the names of God; as an everyday human given name it is common and is presented here in that sense.
