40 kilograms is around 85 pounds. I had to go to the source to check the religion and it was Muslim. This sounds like a test prior to stoning. Balance a rock about the same as your weight or the rocks will fly towards you.
I think it's Hindu. The Ramayana is a Hindu epic, and Sita a Hindu goddess. The writer criticizes the treatment of rape victims in both India and Pakistan, though. "This is no different from the laws that deal with rape in rural Pakistan, which demand a total of four male eyewitnesses..."
I believe the latter requirement is Muslim. "The classical Maliki madhhab doctrine held that a case of rape has the same requirements as proving the case of zina: (1) four male witnesses who testify that they saw the rape and the act of penetration, or (2) confession by the accused." [Wikipedia]
