this is how people agree these days , right

This was the slogan of a campaign against drugs in American schools in the eighties and nineties. Telling teen-agers to "just say NO" when anyone offers them drugs, this slogan was everywhere at one time.

But you're right, it seems there are people who just like to say NO to everything.

so life-makers may use this slogan in their campain these days

Why not? it proved to be very effective in the states.

This is the first time I see the term Life- Makers! Is this your translation or theirs? i

I think that Life-Shapers is more appropriate.

it is not my translation but theirs
they even use this term in their email

Then I suggest that you bring it to their attention. I think that Allah subhanahu is the ONLY Life-Maker

what about the term in Arabic

The term 'sunna3' in Arabic does not have the same connotation as the term 'makers' in English and the same applies to the term '7ayat' which is why I believe that the translation I suggested is closer to the meaning they want.
