Interceding for others on the day of Qiyaamah

Q: When I was 15 my friend asked me to promose to give a testify at the day of Qayamah that he was a good person. But i am scared that if I forgot to keep my promise I will be the one going to Hell, even if I didn't do anything wrong. I made the promise and now I am scared to forget about it as I will have to face Hell instead to him. Is this possible that such contract can be made for Qayamah?
