Have the same problem,
In any case I have visited the Qatar university a couple of days ago with a friend around 08:00 o'clock night and noticed the empty football fields there (5 on 5 or 6 on 6 I think) so you can try there.
Don't know about the rules to use the fields though or if it is free or charged

Anyway if it will be sorted out for you and need players my number 66434485

Best of luck
