Muwatta Malik, Book 50, Hadith 11 (USC-MSA)

Yahya related to me from Malik from Yahya ibn Said from Amra bint Abd ar-Rahman that Abu Bakr as-Siddiq visited A'isha while she had a [health] complaint and a jewish woman was making incantation (ruqya) for her. Abu Bakr said, "Do it (incantation) with the Book of Allah."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرَةَ بِنْتِ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا بَكْرٍ الصِّدِّيقَ، دَخَلَ عَلَى عَائِشَةَ وَهِيَ تَشْتَكِي وَيَهُودِيَّةٌ تَرْقِيهَا فَقَالَ أَبُو بَكْرٍ ارْقِيهَا بِكِتَابِ اللَّهِ ‏.‏
