In accordance with the Qur'an and several hadith, theft is punished by imprisonment or amputation of hands. Several requirements are in place for the amputation of hands, they are:
There must have been criminal intent to take private (not common) property. The theft must not have been the product of hunger, necessity, or duress. The goods stolen must: be over a minimum value, not haraam, and not owned by the thief's family. Goods must have been taken from custody (i.e. not in a public place). There must be reliable witnesses. The punishment is carried out even if the thief repents. [said by Muhammad] All of these must be met under the scrutiny of judicial authority. [Qur'an 5:38]
In accordance with hadith, stoning to death is the penalty for married men and women who commit adultery. In addition, there are several conditions related to the person who commits it that must be met. One of the difficult ones is that the punishment cannot be enforced unless there is a confession of the person, or four male eyewitnesses who each saw the act being committed. All of these must be met under the scrutiny of judicial authority For unmarried men and women, the punishment prescribed in the Qur'an and hadith is 100 lashes.
