I believe that is already in present tense form...
shiftoo (spelling?) means I did see or I saw, so that's past tense
rah'ashoof (spelling?) means I will see, so that would be in future tense
ashoof (or ashouf, I'm not sure of the actual spelling in english of any of these) means I see, which is in present tense
There are multiple dialects of arabic, I think this is more of a slang dialect. If you are taking an arabic language course you're more likely to be taught the proper dialect that you would find in textbooks.
