Traducción - Árabe-Inglés - لا تبالي بنهي أحد واعمل بقصدك جاداً فالثواب فيه....

We can't say "others' forbiddance" in English. What about "others' obstacles" or "others' prevention"?

the one in Arabic i just cant put my hand on, preventing means stopping others from doing something, this one is like: ordering others not to do something, what is the right word fot that?

I think I've found a word that will work - what do you think?

weird, that was my first choice, but i was afraid of YOU LOL
good now we are on the same page

hi Kafetzou, i believe the English one can be tweaked a bit further, may be it should be:
"...And what you had in mind before 'was' wrong."

and one more thing: im not sure about "a reward" it makes it sound like a single reward, but I am referring to the kind of spiritual reward, that cannot be counted... not sure though!

How about "they will be rewarded"?

the reward is within your intentions or working upon your intentions, "they will be rewarded" does not serve the purpose...

I think it's OK as it is.
