I agree to 100 lashes as they are seen in early Islamic Traditions. However stoned to death is something new and I have not heard of this act in life time of Holy Prophet SAW.
As far as I think this is something invested by Talibans in Afghanistan. This world is filled with Zanis and if they all start of confess then pretty soon you will see 70% of the world in graves.
Please provide references for the stone to death from Hadith, Sunnah or Quran?
