How can we define our existence? If there is nothing besides Allah and We are not part of Allah, how can we define our existence without Him or with Him?
Our existence has been created by Allah, The Creator of all creatures. Creatures are never part of The Creator. We exist by His help and Mercy and can never live without His help and Mercy. That can never mean that we are part of Him. Allah Says in Quran : Nothing is like Allah ليس كمثله شيء.
Wassalam.
