Narrated `Abdul `Aziz:Thabit and I went to Anas bin Malik. Thabit said, "O Abu Hamza! I am sick." On that Anas said, "Shall I treat you with the Ruqya of Allah's Messenger (ﷺ)?" Thabit said, "Yes," Anas recited, "O Allah! The Lord of the people, the Remover of trouble! (Please) cure (Heal) (this patient), for You are the Healer. None brings about healing but You; a healing that will leave behind no ailment."
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَارِثِ، عَنْ عَبْدِ الْعَزِيزِ، قَالَ دَخَلْتُ أَنَا وَثَابِتٌ، عَلَى أَنَسِ بْنِ مَالِكٍ فَقَالَ ثَابِتٌ يَا أَبَا حَمْزَةَ اشْتَكَيْتُ. فَقَالَ أَنَسٌ أَلاَ أَرْقِيكَ بِرُقْيَةِ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ بَلَى. قَالَ " اللَّهُمَّ رَبَّ النَّاسِ مُذْهِبَ الْبَاسِ اشْفِ أَنْتَ الشَّافِي لاَ شَافِيَ إِلاَّ أَنْتَ، شِفَاءً لاَ يُغَادِرُ سَقَمًا ".
