This is a summary of what Muslims believe about God. The Arabic word for God is Allah, that is what many Muslims call him as most of islamic texts and words are written in Arabic.
Muslims believe in Tawhid – this is the belief that there is one supreme god. Muslims are Monotheistic, this means they only have one god. They believe that God is eternal, he has always existed and always will. Allah has no gender, no partners and no equals. His nature is beyond our human understanding.
Importance of Tawhid
Tawhid is very important to Muslims. Allah should always be the forefront of Muslims minds. It is the first part of the Shahadah. This is the first thing whispered into a baby’s ear and should be the last thing a dying muslim says. It should also be the first and last thing Muslim says each and everyday. This highlights that Allah is the only one god. He has complete creative power.
Allah is the creator of the Universe and has the power to do anything and everything Muslims believe he is all loving and all knowing. Although Allah has created the whole world and is beyond the universe. he is close at hand. He is immanent. This is the belief that he is close at hand, he is here with us. He knows our unspoken thoughts, he is even closer to us than us than our own heartbeats.
Shirk is seen as the one unforgivable sin in Islam. It means associating other beings with Allah. It is idolatry. If your try to compare Allah to anything in creation, or suggest they have the same abilities , this would be shirk.
