What is the true name of God? Is it ALLAH or Yahweh or what? Where can I find information on the language of Aramaic and the name used by Jesus?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

The real name of God is “Allaah”; this is the name He named Himself with in His revealed Book on the tongue of His Prophets and Messengers, may Allaah exalt their mention.

This name includes all the perfect Attributes of Allaah and He has other Names and Attributes which were mentioned either in the Quran or the Sunnah of the Prophet . For instance, the Prophet said: "Allaah has ninety nine Names". However, the name Yehwah was not included among those Names, and so Allaah should not be called with this name. Allaah Says (what means): {He is Allaah, other than whom there is no deity, Knower of the unseen and the witnessed. He is the Entirely Merciful, the Especially Merciful.} [Quran 59:22] Allaah also Says (what means): {Indeed, I am Allaah. There is no deity except Me, so worship Me and establish prayer for My remembrance.} [Quran 20:14]

As regards Aramaic language, we do not know it and we do not know why you are asking about it. If your intention is to understand religious books and learn religious sciences, then you should learn Arabic which is the language of Quran.

Allaah Knows best.
