اَللَّهُمَّ رَبَّ النَّاسِ أَذْهِبِ الْبَأْسَ اِشْفِ وَأَنْتَ الشَّافِي لَا شِفَاءَ إِلاَّ شِفَاؤُكَ شِفَاءً لَا يُغَادِرُ سَقَمًا

Allaahumma Rabban-nas Adhhibil-ba’s, Ishfi wa Antash-Shafi, laa shifa’a illaa shifaa’uka, shifaa’an laa yughadiru saqama

O Allah, the Lord of the people! Remove the trouble and heal the patient, for You are the Healer. No healing is of any avail but Yours; healing that will leave behind no ailment. Narrated `Aisha (RA): The Prophet (ﷺ) used to treat some of his wives by passing his right hand over the place of ailment and used to say: (The dua is mentioned above)
