Identify dirham

Hi!
I need information on this dirham, which have recently acquired and searching the internet just found this information:

Silver Dirham Ghaznavid dynasty - Mahmud of Ghazni (997 - 1030)


I wonder who put the inscription, the year if is enrolled and mint. All information will be welcome.
Greetings and thanks

Hello
You have got the fishing rod in

Also if you want to identify precisely your coin, read online the classic article
"On the coins of the Kings of Ghazni" by Edward Thomas

Please compare here: perhaps yours is between them

The Obverse and Reverse legends are easy to determine, the margins are always difficult and that is where the mint and date are.  Unfortunately, I don't have a good reference to decipher the margin legends at the moment...

ah yes, looks better
