Bismillah

Thank you for your question. It is important to be well equipped to deal with the arguments of atheists especially if their arguments and opinions have an effect on your faith. In order to do this you should seek out scholars who specialise in the intellectual sciences and speak to them about the issues and questions that remain unanswered for you. They should also be able to help you construct a framework for your beliefs as well as show you the weaknesses in the presuppositions of atheistic beliefs. In the modern study of the philosophy of religion it is well accepted that religious belief is justified. 
 

May you always be successful
