اللَّهُمَّ رَبَّ النَّاسِ أَذْهِبِ الْبَأْسَ، اشْفِهِ وَأَنْتَ الشَّافِي، لَا شِفَاءَ إِلَّا شِفَاؤُكَ، شِفَاءً لَا يُغَادِرُ سَقَمًا
Allahumma Rabban-nasi, adh-hibil-ba'sa, ishfihi wa antash-shafi, la shifa'a illa shifa'uka, shifa'an la yughadiru saqama
O Allah, Seigneur des hommes, enlève le mal. Guéris-le car Tu es le Guérisseur. Il n'y a de guérison que Ta guérison - une guérison qui ne laisse aucune maladie.
