This is in reference to the request for a recommendation letter dated (date). I wish to let you know that recommendation letters are best written by colleagues or superiors who know you abilities and professional qualities well. Since I am from a totally different profession and I hardly know you from past month and that time was not enough to know your professional skills. I think it is, not the right person to judge your merits and professional abilities.
Please don’t take me wrong I know that you are very hard working and dedicated in your work ,I have those information from different sources but professionally if you ask me I will not be able to write as much as easily compared to person one from your department. I feel really great that you selected me to write a recommendation letter .I will not be able to write with authority and clarity the qualities and your best points. I would suggest that you should approach someone else.
It’s with regret I refuse to write this letter and I hope you understand the reason fore declining.
If I can help you in any other way please feel free to ask me. Wish you very best of luck.
