The following video discusses an intramural conflict within the congregation of a mosque in The Hague. The translator includes these notes about the situation:

Police became involved; the victims will file complaints with them. The Pakistani cult is called Hijaz. As might be suspected from their accents, the mosque was founded by Muslims from Suriname. They’re descendants of coolies who came to Suriname from Hindustan, north of India. They’re Ahmadi, not known for extremism.

Many thanks to C for the translation, and to Vlad Tepes for the subtitling:
