Those who dont believe in Mehdi(A.S)[whether as a mujadid or as an Imam] will be the first ones to fall under the influence of Dajjal.
Fitnah-e-Dajjal is not a mere fairy tale as many “progressive muslims” now believe it is very much a central belief in Islam.
You guys are very funny.....but just some advice...lets dont get carried away with jokes. The mehdi is real as is the dajjal, and specially with the times we live in today....it wouldnt be surprising if the "real deal" appeared during/after the hajj.
