Kasam, Kasab, Kasav, Qasam or Qasab...wats actual?

Kasam ?-Kasav ?-Kasab ?-Qasam ? or Qasab … The only surviving gunman of the massacre in Mumbai got several names in India other than one his parents had found for him. Some of these are just differences in transliteration (Kasab vs. Qasab, for instance), but the rest would seem to be the product of a sloppy media culture and bad press management by officials. Azam Ameer Kasab also spelled as Azam Amir Kasav/Quasb.
