Answer:
Dear ...,
I ran into your sister this morning, and she told me you had suffered a car accident and that she was on her way to the hospital. I can't tell you how sorry I am! I know you are always careful when driving, so I immediately knew it was the other driver's fault, which was confirmed by your sister. She told me you're in ... Hospital. I will be coming to visit as soon as it's allowed - I was told you can only see close family members for now.
If you and your family need anything, do not hesitate to contact me. I'd like you to know that I am here to help, day or night. I will never forget that time I was in an accident myself, and you were there for me, helping me stay strong. I will be forever grateful! I wish you a speedy recovery, my friend! I will be seeing you soon, alright?

The passage above has about 160 words. Please, include your name and a friend's name, as well as the name of a hospital in your town.
When writing a letter, message, or email to wish a speedy recovery, it is nice to say a few comforting words and remind the person that you are there for them. At difficult times, it makes a huge difference to know a friend is available to help.
