Molana Saad’s followers have resolved that they will conduct Quran Translation Halqas in the masajid.

Answer

No, it is not proper for them to engage in Qur’aan translation halqas. If they do so, it will mean that they are forming another sect. They will then no longer be regarded as even a faction of the Tabligh jamaat in view of transgressing the Six Points which constitute the fundamental basis of the Tabligh Jamaat.
