Yes, it's from Arabic, but though Persian.
Borrowed from Persian آدمی (âdami), from Arabic آدَمِيّ (ʾādamiyy, “human”), from آدَم (ʾādam, “Adam”), from Proto-Semitic *ʾadm-.
In Arabic, Adam only means the name of the prophet, in Hebrew, it means "red". אדם, or from Akkadian adamu meaning "to make", or from the color of the red clay used by God to make the first man.
I HAVE MADE A SUPERGROUP Seriously, No means of communication in the app makes me sad. It could have been a great opportunity for us to communicate productively and that could seriously boost our language learning capability.. I have an idea, I have just made a telegram group which has an inherent capacity of 200000 members, Which is pretty huge I think. Telegram is an app like WhatsApp, messenger...You can download the Telegram app from google play store or from the app store, also there are windows and web versions of telegram. I am going to post the link of the group below, all interested persons can join directly via the link below...The main purpose of the group is to communicate with each other so that our language learning endeavor could get a boost, so hope to see you all there....Take care..

Actually there are 2 meanings of raj, one is secret another is to rule...
Mujhe is sahar mein raj karna hain (I have to rule in this city)
Main aj hamare is mulakat ko ek raj rakhna chahta huun(I want to keep our todays meeting a secret).
Hope this clarifies all the common doubts regarding 'Raj'
