In my school, I tend to spend lots of time praying, especially in sajdah saying a number of duas, and I am sometimes a few minutes late for my classes. Is there a short or one dua that is very rewarding as if you spent lots of time in sajdah reciting many duas, or something similar to it?

Also is there a dua to hopefully hasten the traveling to the Holy Shrine of Imam Husain (Alayhi Salam) in Karbala? My dad is going there and I want to come with him, but he is unfortunately not agreeing, due to some possible problems.
