Answer»

My reaction would be that of gratitude to God and the company. Of course I will be happy on getting the promotion. When I am in a better position I will be able to give better service to people.

Dear Director, Dr. Cronin, respected officers and crew members, I am so happy to be given this kind of recognition by the Company and the officers. I don’t think I did anything great in serving the sick people in the ship.

Wasn’t it my duty to serve the suffering? Allah has given us this life to love and serve others. When we get a chance we should be able to of service to others.

I am a Muslim. But I believe we all are children of God. That is why I even read from the Ramayana some relevant part when I sewed the shroud for the dead people and wanted to cast them overboard. I was not worried about getting the disease because I felt that life is a gift from God. He will take it way whenever he likes. Whatever precautions you might take, you can’t prevent death from coming to you.

I don’t value money or position much. But I am happy that I am given promotion because it will help me to do more service to my brethren. I would like to end my humble words with a quotation from the Bible. It asks: What is the use of earning so much wealth in this world,’ if you lose your soul? So my advice to my friends is ‘Help others as much as possible.’

Before I close I want to thank Dr. Cronin and the Chairman for giving me the promotion. I assure them that I will continue doing my best for the Company. May the Almighty Allah bless you all and thank you.
