Does teaching English to the imam of the mosque come under the heading of cooperating in sin and transgression?
Question

                We have a new imam in our community. He graduated from al Azhar. Although there is some good points about him, he seems to have an incorrect manhaj and is a little bit loose. He does some of the smaller things such as keeping a very short beard and other things. My question is, my parents commanded me to teach him english. Will this be part of the ayah which says do not help each other in wrongdoing since he may use this english to teach this incorrect manhaj. For the time being, there seems to be more good than bad from him, however, he may change as he stays in this kaffir country. Please advice me.
Praise be to Allah.What your parents have 
    asked you to do of teaching this imam does not come under the heading of 
    cooperating in sin and transgression. The fact that this imam goes against 
    sharee’ah in some issues means that you have to advise him and remind him 
    lest he continue with those infractions and fall into others, especially as 
    you are going to form a special relationship with him by teaching him 
    English. 
Cooperating in sin and 
    transgression would be the case if you were to be the cause of some sin or 
    continuing it or spreading it, or if you helped the one who is doing it with 
    some idea or money or physical help. 
Examples of cooperating in 
    sin and transgression include: renting out stores to riba-based banks or 
    stores that sell haraam things, joining a businessman in manufacturing, 
    selling or buying haraam things, or helping followers of bid’ah (innovation) 
    financially or by enabling them to speak to the Muslims, and so on. 
In the verse 
    (interpretation of the meaning): “Help you one another in Al‑Birr and 
    At‑Taqwa (virtue, righteousness and piety); but do not help one another in 
    sin and transgression” [al-Maa’idah 5;2], Allaah enjoins His believing 
    slaves to help one another to do good deeds, which is righteousness, and to 
    avoid bad deeds, which refers to piety; and He forbids them to help one 
    another in falsehood or cooperate in sin and haraam actions. 
Tafseer Ibn Katheer 
    (1/12, 13) 
Because this imam has some 
    good qualities, we hope that you can strengthen them and help him to fulfil 
    them and attain more. This will be cooperating in righteousness and piety. 
    As for his bad qualities, we hope that you will denounce them and advise him 
    to give them up, and this will also come under the heading of cooperating in 
    righteousness and piety and the sincere advice that is required of Muslims. 
     
It should be noted that the 
    fear about this imam being influenced by staying in the land of kufr does 
    not apply only to him, rather it applies to him, to you and to all the 
    Muslims. What we have seen and heard is sufficient proof that people are 
    influenced. 
We have previously stated 
    that it is not permissible to stay in a kaafir country unless one has a 
    legitimate shar’i excuse and meets the conditions laid down by sharee’ah. 
    This has been explained in the answers to questions no.

And Allaah is the Source of 
    help.
