I made a whatsapp group, because a salafi was starting to teach ppl how to read quran and arabic. But deobandi imam of the masjid forced that he himself teach people how to read quran, and arabic lessons havent started yet, what to do with the group? BTW salafi may start teaching arabic soon(ish)

Ustadh AbdulAziz al-Haqqan

Well, u should only take from those that are well-trusted like the salafi brother, as for someone that is not trustworthy you can remove him from the group, or make another group without him, you know best how to deal with it in sha'a Allah.
