A molvi who is employed by SANHA gave our Imaam a stack of pamphlets for distribution in the Musjid.

Answer

Removal of the haraam pamphlets did not serve any purpose. The haraam chicken saga is now known to almost all Muslims. No one is in any darkness in this regard. Those who are addicted to devouring haraam, diseased carrion chickens will continue doing so regardless of the evidence being as clear as daylight. They consume the rotten chickens not because they follow SANHA whose certification they cite merely as a front for their own immoral villainy. A drug addict remains hooked on drugs regardless of mountains of evidence to prove that drugs are haraam. However, if he finds a molvi with a forked tongue to give him a crooked interpretation, e.g. it is merely a plant which is taahir, hence halaal, then he will justify his addiction with the forked-tongue molvi's/ sheikh's interpretation. On the other hand, those who have some fear for Allah Ta'ala and a proper conception of haraam and halaal will abstain from consuming shaitaan's food (the carrion chickens of SANHA and MJC) without any argument.

Since you are not a trustee of the Musjid nor the Imaam, you should not have uplifted the pamphlets despite the haraam corruption which SANHA is propagating. Your action can lead to anarchy and unnecessary argument and even violence with carrion-consuming thugs.
