Bismillah,
We have to aim for our deen to be as pure as it was revealed to the prophet(saws).
In terms of Deen we have to go back to the good old days of the Rasul(saws).
Innovation in deen leads to Jahanam.
For Dunya it is the opposite.
We need to go forward(progress) with the times.
This is the 21st century.
Innovation in technology(and Dunya) is acceptable.
WE have to live in this two centuries at the same time, giving priority to the 7th century(Deen).
That does not mean we have to live in the "dunya" of the 7th century.
We only need to live in the Deen of the 7th century.
I don't see any contradiction.
why do we confuse the two?
Why do we need to go back to 7th century "dunya" or innovate Deen to the 21st century?
