I am worried about myself or a family member contracting an incurable disease, and my work in a medical environment heightens this fear. Is there a specific Dua that can help alleviate my anxiety regarding this situation?
There are many supplications for protection beside repeating Estighfaar and Salawaat and giving Sadaqa. These supplications are mentioned in many books like Mafateeh Al-Jinan. One of these Du'as is (أُعيذُ نفسي وديني وأهلي ومالي وما رَزَقَني رَبِّي بالله الواحد الأحد الذي لم يلد ولم يولد ولم يكن له كفوا أحد.
(O'EETHU NAFSI WA DEENI WA AHLI WA MAALI WA MACRAZAQANI RABBI BILLAH AL WAAHUD AL-AHAD ALLATHI LAM YALID WALAMBYIULAD WALAMBYAKON LAHU KOFOWAN AHAD)
Wassalam.
