I was reading an article on proof of existence of Allah, not that I need it, but more for dawah purposes and inshaAllah will increase my imaan too. I'm having trouble understanding this paragraph. If any philosophical people out there can clarify, that'd be great. Here it is: The direct opposite of ‘Everything which begins to exist must have a cause’ is ‘Not everything which begins to exist must have a cause’, which is in the power of ‘Some things which begin to exist do not have a cause’. Anything which begins to exist by definition can not be necessarily existent [whether such a category actually exists or not is not the point currently. Our opponent is free to believe that it is purely hypothetical]. Otherwise it would have been existent since eternity past, since necessarily existent means its very nature requires for it to exist in which case it cannot have a beginning for its existence. Similarly, it can not be impossible because impossible things do not happen in which case it would not have begun to exist. Since such a thing can neither be necessary, nor impossible, it must be merely possible (another word for which is contingent). Therefore, with respect to the very nature of such a thing, both existence and non-existence are equal. That it is to say, there is nothing in its very nature which requires existence (since it is not necessary), nor is there anything in its very nature which requires non-existence (since it is also not impossible). Thus the two are indeed equal. taken from : http://www.deoband.org/2010/03/aqida...-of-a-creator/
