I agree with you 100%. This was how it was done at the time of the Prophet Peace be upon him & his companions. In fact there was an incident where 3 men accused another of adultery claiming they saw the act but because they didn't have a 4th witness they the accusers were punished instead. Such is the shariah when practiced the right way according to the sunnah. But I repeat how far is Iran from the sunnah?very very far. Do you know how many sunnis are killed & oppressed merely for following the sunnah? But God is Just & may the lady in question get her justice..Aameen!
