Mukhtasar Muslim

Narrated from Umm al-Mu'mineen Umm Salamah (may Allah be pleased with her): When any of us would fall ill or suffer a wound, the Messenger of Allah (peace and blessings of Allah be upon him) would place his index finger on the ground and say, "In the name of Allah, the soil of our land, with the saliva of one of us, so that our sick may be cured by the permission of Allah, the Exalted."
