Assalamualaikum w.b.t
As you know, today will be my last day here in [company] I would like to take a second to thank each and every one of you especially [department] for helping to create such a satisfying and pleasant work environment over the last XX month.
As happy as I am to be moving on to the next chapter of my life, I have enjoyed (almost) every moment here, from the hilarious conversations in the mamak stall, to the numerous staff events such as futsal.
But, beyond this, most of all I truly appreciate the support and guidance that was always available to me. So, thanks again everybody. Its been quite a ride. I hope to see everybody outside of the office in the other day.
Sincerely,
(your name)
