Hello dear friend !!!

Let me explain you ,

HCl gas gives H+ ions only in aqueous solution.So it will not split into H++ Cl- in the dry Litmus Paper no reaction occur.

With wet Litmus Paper water acts as a career for splitting the HCL into H+ + Cl- . Then reaction occurs and turn the blue Litmus to red.
