سنن ابن ماجه

It was narrated from ‘Aishah that one of the things that the Prophet (ﷺ) used to say for the sick person, with saliva on his finger (dipped in dust), was: “Bismillah, turbatu ardina, biriqati ba’dina, liyushfa saqimuna. Bi’dhni Rabbina (In the Name of Allah, the dust of our land mixed with the saliva of one of us, to cure our sick one by the permission of our Lord).”
