Bulugh al-Maram, Book 10, Hadith 1267 (English)

'Aishah (RAA) narrated that Allah's Messenger said: "A thief's hand should not be cut off except for a quarter of a Dinar or more." Agreed upon and the wording is from Muslim. The version of Al-Bukhari reads, 'The hand of a thief is to be cut off for a quarter of a Dinar or more."

عَنْ عَائِشَةَ رَضِيَ اَللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-: { لَا تُقْطَعُ يَدُ سَارِقٍ إِلَّا فِي رُبُعِ دِينَارٍ فَصَاعِدًا } مُتَّفَقٌ عَلَيْهِ.‏ وَاللَّفْظُ لِمُسْلِم ٍ (1595)‏.‏ وَلَفْظُ اَلْبُخَارِيِّ: "تُقْطَعُ اَلْيَدُ فِي رُبُعِ دِينَارٍ فَصَاعِدًا " (1596)‏ ‏4 ‏- صحيح.‏ وهذا لفظ مسلم (1684)‏.‏‏5 ‏- البخاري (6789)‏.‏
