«الزَّانِيَةُ وَالزَّانِي فَاجْلِدُوا كُلَّ وَاحِدٍ مِنْهُمَا مِائَةَ جَلْدَةٍ»
For each of the two specified offenders, the verse states one hundred lashes.
Within its applicable classical legal context, the verse fixes the stated quantity. The question here is whether a report may add another mandatory component to that very prescribed punishment. The distinct procedural requirements of evidence and judicial implementation are not supplied by this excerpt; enforcement belongs to lawful judicial authority, never private action.
