Take the following as truth: Mahmud smashed the infidels' idols and destroyed their temples as he went, but was nonetheless cultured enough to use the booty to build a library, a museum, and a splendid mosque when he got back to Ghazni.
Then the following statement: "In addition, Mahmud also erected a large marble monument in the city of Ghazni." is true, false, or inconclusive?
