The Hindu Custom called Jauhar
From 1300-1600 the women of the warrior caste called the Rajputs,who live in Rajasthan,India, commited mass suicide on several occasions:
1.To avoid being made sex-slaves of the Muslims.
2.They generally burned themselves to death.
3.It was done when it was 100% certain a city or fort would be taken by the Muslims.
4.The Koran authorizes a Muslim man,even those who are married,to have sex with a woman who is their slave and even the right to have a Muslim woman as his slave.
5.For us it is adultery,for the Koran it is not adultery.
