Surah Al-Ma'idah, ayah 38

5:38

وَٱلسَّارِقُ وَٱلسَّارِقَةُ فَٱقۡطَعُوٓاْ أَيۡدِيَهُمَا جَزَآءَۢ بِمَا كَسَبَا نَكَٰلٗا مِّنَ ٱللَّهِۗ وَٱللَّهُ عَزِيزٌ حَكِيمٞ ٣٨

Was-sāriqu was-sāriqatu faqta'ū aydiyahumā jazā'a bimā kasabā nakālam minallāhi wallāhu 'azīzun hakīm

[As for] the thief, the male and the female, amputate their hands in recompense for what they earned [i.e., committed] as a deterrent [punishment] from Allāh. And Allāh is Exalted in Might and Wise.
