Respectfully, Most of my brothers who are abusing Maharaja Ranjit Singh should do one thing.
If you are a Punjabi, Ask about him from any of your elders who was born in 40s or 50s and not associated with any Hardcore Religious Jamaat. Ask him how Muslims used to View Maharaja Ranjit Singh before this mindwash galore of late 70s and 80s took place.
Ahmad Shah Durrani Plundered These Lands.He was part of Nadir Shah Armies who Slaughtered Delhi before. Durrani Entered our lands by defeating Shahnawaz Khan of Peshawar. and subsequently Muin ul Mulk of Lahore. These Raids were the reason mughal hold in KPK Punjab Kashmir Region was lost, And Local Sikhs rose to power, Maratha rose to power in northern Hindustan. and the chain of events that caused the rise of Sikh empire. Arch Rival of Ranjit Singh, the Durrani Empire was an offshoot of the chengis khan Incarnate Nadir shah Afsharis empire, not some holy Muslim Empire representing the Caliph in Istanbul. Don't Bring Islam in these wars. People like Mir Temur, Nadir Shah and his followers were open admirers of Mongol Khan Chengis khan. Only Allah knows whats in heart but mass slaughter of cities is not what muslims do, It was what mongols did. And so did these sons of Mongols Calling themselves Muslims and Tainting our religion with their heinous acts.
Ranjit Singh Defeated Ahmad Shah Durrani Son Zaman Shah. He will always remain a son of Punjab who broke the teeth of Durrani Invaders. If some one wants to associate with Nadir Shah Offshoots more then his own ancestors then be my guest. But first read the history without bias. And Ask from your elders who are most reliable source of information instead of Propaganda Books.
Singh wars against Afghans. Like any war, Some local factions sided with durranis some sided with Ranjit. Even Some Tribesmen sided with Ranjit Singh against Durrani Empire. Even Sultan Shuja Khan Durrani sided with Sikhs when he was exiled. (War is war). And Just think why every governor of these Punjabi and Siraiki cities were all Afghans not locals when Ranjit Singh Took over them from Durranis.
Its really Cringe worthy how our Historians try to portray how everyone from west of Pakistan was part of a unified Muslim Rule and savior of Muslims. People here don't even know that Ahmad Shah Durrani (An Afghan Warlord who break away from Nadir Shah Armies after his death to created his own Dynasty) and early muslim conquerers like Sultan Mehmood Ghaznavi were 750 years apart from each other.
If you believe all of the above to be true(He was a tyrant who subdued your ancestors and so on) then you have every right to hate him and as you said P*** on his statue and so on.
But will you rather "P*** on statues" of Mir Temur and Nadir Shah as well? Their cruelty is matched only by Chengis khan and Halagu khan. Muslim Historians write about them that they slaughtered whole cities and made minarates of decapitated Heads outside the defeated cities that resisted their conquests, Just as Mongols did (Confirm it from any sources you believe except Naseem Hijazi saab Of course). Will you sir, in Principle, P*** on them as well,as you will do with Ranjit Singh?
