Hu or Huwa is a name for God in Sufism. Literally: He. God. [1]
In Sufism Hu or Huwa is the pronoun used with Allah or God, and is used as a name of God. Allah Hu means "God, Just He!" In Arabic Allah means God and with Hu, as an intensive added to Allah, means "God himself." Hu is also found in the Islamic credo La Ilaha Ila Allah Hu: "There is no God but Allah," or in Sufi interpretation "There is no reality, except God", or in La Ilaha Ila Huwa meaning "There is no god but He" [2]
The term Hu in reference to a creator or god is linked to many cultures and religions. The ancient Egyptians [3] and the Druid are just a few.[4][Proper citation required on druid statement, the link does not mention druid.]
Non-Muslims may speculate that the pronoun when used by the Sufi (and Muslim) is simply a shorter form of the Hebrew Tetragrammaton due to the similarities between Sura Al-Ikhlas 112:1 in the Quran [5] and Deuteronomy 6:4 in the Hebrew Bible. [6]
