Those who are well versed with hisory must be knowing about this Alberuni who is known as a "scholar","historian", "a scientist" to the western Muslim world. But his loathsome act of replacing the head of the spear with a poisonous one testifies that these "melechhas" 🤢 as they were always referred, could never be trusted.Even in a game or duel or war one cannot expect them to put put up a fair fight.
This race was never trustworthy and were always backstabbers.They were simply barbarians who knew no rules , observed no humanity, never respected other peoples religious sentiments and felt sort of achievement in defiling their sacred temples, looting them and abducting their women and defiling them, calling them as kaafirs and converting them at the point of sword .
History has ample evidence from Ghazni to ghori , babar to khilji, aurangzeb to tipu who were a race with no scruples and could never be relied upon.This continues even till today where we being gullible and fools have time and again trusted them and got backstabbing in return..
