Forgotten iPhone restrictions passcode - how can i find it out?

I got an iPhone 5s today, and I'm giving my old iPhone 4 to my dad, so i need to erase all the settings on it. I went Settings> General > Reset > Erase all content and settings
It's asking me to put in my restrictions passcode… I have no idea what this is, and have used 8 attempts to put in things it could be, like 0000, 1234 etc. Nothing has worked. Is there a way to get around this so i can restore the phone and give it to my dad?
