Write a letter to your friend consoling him on the death of his mother.

Dear Farjana,

I hope this letter finds you well. I wanted to share some thoughts with you. You know, people aren't immortal; they can't live forever. Everyone has a time when they'll pass away, some sooner and some later. But while they're alive, they have things to do in this world. If they manage to do those things, they can be called successful.

I was shocked when I heard that your mom passed away suddenly. It was unexpected, like a surprise that hits you out of nowhere. I had visited your home not long ago, and she seemed perfectly fine. But life is unpredictable, and we can't know when someone will be taken away by death. Losing your mother is a very sad thing, and I can imagine how much pain you must be feeling. I wish I could make you feel better with comforting words, but I know that's not easy right now. All I can say is, try to stay strong and patient even though it's really tough. 

I hope your mom's soul finds eternal peace. My thoughts are with you in this difficult time.

Take care and sending you my best wishes.

With love,

Samia
