Why do Jehovah's Witnesses call God Jehovah?

They regard this name as the only proper one. From the point of view of Islam, however, it is the same one God whichever name one calls Him by, because all beautiful names belong to Him.

Jehovah's Witnesses attach great importance to addressing God by the name they derive from the Hebrew Bible. For them it is a sign of true loyalty. One can respect this intention and still ask whether God is really bound to a single name.

God has made Himself known to people in every age, in different languages and with different forms of address. In the Holy Qur’an He is called Allah. Often the Holy Qur’an also speaks of Him simply as "He", the One beside whom there is no other. The Bible, too, knows several names and forms of address for God. All these names point to the same one God.

So it makes no difference by which name one calls upon Him, as long as one means the one true God. The first verse above says this explicitly. Whether one says "Allah", "the Gracious" or "my Lord", it is always He who is meant. His names describe His attributes, as the second verse shows, for example that He is the Creator and the All-Wise.

An argument about the right name therefore divides people who are in fact seeking the same God. More important than the question of the word is the question whether one recognises God as the One and serves Him alone.
