Sunan Abi Dawud, Hadith 3881 ⓘ
Anas said to Thabit : Should I not use the spell of the Messenger of Allah for you ? He said : Yes. He then said : O Allah, Lord of men, Remover of the harm, heal, Thou art the healer. There is no healer but Thou; given him a remedy which leaves no disease behind.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ بْنِ صُهَيْبٍ، قَالَ قَالَ أَنَسٌ - يَعْنِي - لِثَابِتٍ أَلاَ أَرْقِيكَ بِرُقْيَةِ رَسُولِ اللَّهِ قَالَ بَلَى . قَالَ فَقَالَ " اللَّهُمَّ رَبَّ النَّاسِ مُذْهِبَ الْبَاسِ اشْفِ أَنْتَ الشَّافِي لاَ شَافِيَ إِلاَّ أَنْتَ اشْفِهِ شِفَاءً لاَ يُغَادِرُ سَقَمًا " .
