I know just one thing and that is to follow the IMAM. Full Stop!
If everyone starts constructing its own 2 inch mosque, you can well imagine where the Muslim world will be. If everyone starts doing sajda on his own will while praying, there will be no unity and no prayers.
Mufti Muneeb might be wrong, but if he is deliberately wrong he will be answerable to Allah, not anyone who is following him. just like when any imam makes mistake in Namaz.
If the state make that fitna Popatzai as the imam, I will have no problems following his orders even if he announces Eif after 28th Roza. But right now, he is a fitna, big big fitna who is dividing the nation and you guys are his dumb followers just like MQMers are followers to Tafu Mirasi
