More hindutva saffron wash of history
Omitted the primary reason of conflict the pirates under patronage of dahir attacking and abducting Muslim ships
As for conflict with Arabs dahir did faced two armies prior Qasim but that wasn't in 30 years time but with in year or two of that piracy episode after that the teen general came and defeated a far more experienced raja who had much bigger army due to obvious home filed advantage
Also its funny that according this bs dahir old wife committed johar but his two youthful daughters
And this bs also fogot to mention that dahir forced marriage his own sister which caused a war between him and his elder brother who died in mysterious manner allowing dahir to usurp his kingdom and reason makran and other local allied with Qasim because they got fed up with dahir looting and intimidation of their territories
