Dear Sir
I am a senior Engineer who has spent over 20 years in the Gulf (Arab Countries) and I can speak, read and write Arabic as I am a Muslim.
Besides religious books in Arabic, the love of reading got me into looking at Arabic newspapers when I was in Saudi Arabia, Dubai, Qatar, Oman and also Yemen.
Moreover, I am from the city of Hyderabad itself, nearer to Charminar where we have that famous bookseller Mohi & Haziq. That guy is famous for old books in Arabic and a collector's dreamshop.
Since I am out of active employment from Arab countries with declining oil prices and all that stuff about economy, I am now almost retired and hence this gives me ample time to pursue matters which interest me, as in your case.
If you are Westerner, you might see that I write English as well and this comes from working with White folks while I was in Arab countries.
Some of the companies I worked for are: Canadian Nexen Oil-Yemen, Dove Oil Co.-UK, Total E&P France, and others.
As I love reading, my favorite books/characters are: James Hadley Chase, Perry Mason-ESG, Agatha Christie, Nick Carter, A Catcher in the Rye, etc.. the list goes on...
I think based on my experience, I can go and check that bookstore and get you what you would like.
I can speak local languages URDU, HINDI and most important in Hyderabad is TELUGU which I know very well.
Based on all above facts, looking forward to hearing from you soon.
Thanks/Bye
