My dear Sana,

Assalam-o-Alaikum!. I am very sorry that I cannot attend your birthday party because preparing for tomorrow's sandup exam, anyway, I wish you a happy birthday. I bought a special gift for you. I was going to send you by mail but my father told me that you are coming to meet us on the 20th. So, we decided to give this gift to you personally.
Salam to all at home.
Yours sincerely,
X.Y.Z
