Do NOT let the secularists and communists take advantage

بِسۡمِ ٱللَّهِ ٱلرَّحۡمَٰنِ ٱلرَّحِيمِ

Do NOT let the secularists and communists take advantage of differences amongst Muslims, even if some of the differences are that of Sunnah and Bidah
Sheikh Muqbil bin Haadee, may Allah have mercy on him..
"Be careful that you let a communist, or socialist, or Naasiree, and anyone like them from the people of misguidance come and instigate trouble between you because of whether or not to say ameen after Al-Fatiha, or adding something to the adhaan, or whether or not to place the hands on the chest. All of you are brothers. Your Lord is One and your book is one.

The one who acts according to the sunnah will be rewarded. And the one who contradicts it after knowledge has come to him, we fear for him sin and that he will be punished. But the communist, or the one who doesn't pray (or any other trouble maker) comes and instigates trouble between us then gloats over it, my brothers, to continue deceiving us. They say "look at them arguing and fighting in the masjid, fighting over words added to the adhan."
Yes, adding unlegislated sayings to the adhan is bida'. Don't do this, those of you calling the adhan and doing so. And, saying ameen after Al-Faatiha is from the sunnah. But the one calling the adhan, adding to it, the one who doesnt say ameen, and the one who doesnt put his hands on his chest is still your Muslim brother EVEN IF HE IS AN INNOVATOR."
