After lot of reading on this topic i conclude a simple solution that there is not any mystic part in Islam.That why it is called siraat e mustaqeem(Straight Path) and valid till the Armageddon. If it is mystic than how can Allah make a hidden or vogue version of his saying valid till Armageddon.

Any way Some orientalist and researcher consider the Holy Journey Of Prophet(PBUH) (MIRAAJ) as the mystic and start of the mysticism in in Islam from that Journey.
