Ok now that is some joke...are you writing NCERT History books for Congress caders...Sati was abaolished by movemets during Indepenence. It had NO Islamic roots at all...! Infact even today Muslim women are subjects of oppression under their husbands.
Talking of Culture, IF anything the Muhals only tried their best to destroy it. Like you they also thought destroying temples and statues will destroy Culture. They didn't understand that it is embedded in the way of life of every Indian.
Don't come and repeat what your moulwi brains washes you abt history. Most likely this dude didn't even go to school.
