Knowledge of Hell and Heaven is with ALLAH.. i believe the unseen…Maybe they are physical maybe not.. i don’t know.. But i think that they must be physical..becoz on the day of judgment people will be alive with their bodies physically, its my own thinking.. and ALLAH knows the best..
But i think you are making a big mistake here.. you mean that EVERYTHING should be rational and acceptable (according to yur relegion), But.. its not like that.. you can feel and see and feel only a few things..by yur senses.. but it doesn’t mean that its all what you see.. but its actually yur ignorance.. our thinking is limited.. even we can not think of infinite… and thats where you people are most ignorant.. where you want to be everything rational and understandable according to physical world.. No my dear.. you are mistaken.. you follow the modern Godless world of acquiring knowledge through sense, perception and rationality.. This is Not true..I believe that ALLAH SWT WHO is the CREATOR of physics.. CAN Nullify and hault it at any time HE wants.. Just like HE did at the time of Miraj-e-Nabi (S.A.W.W).. or at the time of Hazrat Isa (A.S).. Physics is bound to follow HIM.. HE is not bound to follow physics..
