Muwatta Malik, Book 41, Hadith 23 (USC-MSA) ⓘ

Yahya related to me from Malik from Abdullah ibn Abi Bakr from his father from Amra bint Abd ar-Rahman that a thief stole a citron in the time of Uthman Uthman ibn Affan ordered its value to be estimated and it was estimated at three dirhams at the rate of exchange of twelve dirhams for the dinar, so Uthman cut off his hand.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرٍ، عَنْ أَبِيهِ، عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ سَارِقًا، سَرَقَ فِي زَمَانِ عُثْمَانَ أُتْرُجَّةً فَأَمَرَ بِهَا عُثْمَانُ بْنُ عَفَّانَ أَنْ تُقَوَّمَ فَقُوِّمَتْ بِثَلاَثَةِ دَرَاهِمَ مِنْ صَرْفِ اثْنَىْ عَشَرَ دِرْهَمًا بِدِينَارٍ فَقَطَعَ عُثْمَانُ يَدَهُ ‏.‏
