Can Khutba on fridays can be delivered in regional languages. Or its a must that it should be in Arabic.

Praise be to
Allaah.

The Friday khutbah is an act of worship
which should not be done in the local language. But if there is no one
present who speaks Arabic well, then it is OK to say what the people
present will understand. If the people present do not understand Arabic
then it is OK to translate what they need to know for them after the
prayer, or to explain to them in their language what they need to know.
