Fathwa - What can be (or is) the minimum Mehar these days?

Q:What can be the minimum Mehar these days?
A:Minimum Mehar is ten Darm and ten Darm is seven Misqaal and one
Misqaal is 4.5 Masha. Therefore ten Darm will be Two Toala and 7.5
Masha Silver in weight. Itis equal to 30grams, 618milligrams.
Thereforewhatever it costs to buy that much Silver will be Mahar; it
cannot be less then that. In Summary the fluctuation in the amount to
buy that much silver will reflect Mehar.
Allah Tala knows the best.
