Hadith 14:156
Abu Bakr narrated to us, he said: Ibn ‘Uyaynah narrated to us, from ‘Abd Rabbih, from ‘Amrah, from ‘Aishah, that the Messenger of Allah (may Allah bless him and grant him peace) used to say to the sick person, while placing his saliva on his finger: "In the name of Allah, the soil of our land, with the saliva of some of us, heals our sick, by the permission of our Lord."
حدثنا أبو بكر قال حدثنا بن عيينة عن عبد ربه عن عمرة عن عائشة أن رسول الله صلى الله عليه وسلم كان مما يقول للمريض ببزاقه بأصبعه بسم الله تربة أرضنا بريقة بعضنا يشفي سقيمنا بإذن ربنا
