In The Two Sahihs it is narreted that Aishah (Radiyallahu Anha) Said:
« كان رسول الله صلى الله عليه وسلم ، إذا شتكى الإنسان أو كانت به قرحة أو جرح ، قال بإصبعه هكذا – ووضع سفيان سبابته بالأرض ثم رفعها- وقال : باسم الله تُربة أرضنا ، بريقة بعضنا ؛ ليشفى به سقيمنا ، بإذن ربنا » ( البخاري : 5745)
Whenever a person would complain from an ulcer (or a canker), or a wound, the Messager of Allah would put his finger in the soil (on the ground after inserting it in his mouth, then raise it), saying, ' In the Name of Allah: with the soil of our earth moistered with the saliva of some of us, let our sick be cured, with our Lord's permission.
"This is an easy, beneficial cure for the various ulcers and fresh wounds, especially when there is no available medicine. The sand, which is cold and dry and is available on all parts of the world, dries out the moisture that accumulates around the ulcer or wound. This moisture prevents quick healing by natural means, especially in warm areas. Most ulcers and wounds are also accompanied by a hot fever, which, when added to the irritant of warm weather, would only intensify the pain of those who are especially sensitive to heat. Since pure sand is cold and dry, more cooling than even the most effective medications for this purpose, the coolness of the sand will effectively pacify the warmth caused by the wound. especially when the sand is washed and dried. Pure sand also helps dry out most harmful moistures and wetness, because it is a strong drying agent against the wetness that prevents quick healing, as we stated. Further, pure sand helps cool the hotness in the ailing organ which will strengthen its power of resistance (immunity) and thus end the pain by Allah's Leave.
The Hadith indicates that one should place some saliva on his index finger than place it on pure sand, some of which will stick on to his finger. The finger should then be placed on the affected organ or the wound, and then one recites the supplication mentioned in the Hadith. This practice joins the blessings of mentioning Allah's Name, relating all matters to Him and trusting in Him, adding both the cure and the supplication that will make the remedy even more effective.
There are two opinions regarding the Prophet's statement, " The sand of our land ", if whether it entails the sand of the entire earth or just the sand of Madinah. There is no doubt that some types of sand are more effective remedies for various ailments than sand from other areas. Galinus said, " In Alexandria, I saw many people who suffer from severe dropsy and an ailing spleen use the sand of Egypt as ointment on their legs, thighs, hands, backs and ribs, and they used to benefit from this remedy. " He also said, " Hence, this ointment (muddy sand) could help cure Putrid and limp tumors. " He continued, " I know of many people, whose bodies have swollen due to excessive bleeding. who benefited from remedy using mud. I also know of others who used it to cure terminal illnesses that attacked various organs, and the terminal ailments were eradicated. "Another author said, "Sand that is imported from the area of Kannus - known as the island of Mastic - is an effective cleanser and causes the flesh to grow in and around ulcers, thus effectively eradicating them.
" Since various types of sand have a healing effect, what about the sand of the best and most blessed area on the face of the earth, especially when mixed with the Prophet's saliva? Added to these blessings is the supplication that the Prophet (PBUH) recited and in which he mentioned the Lord's Name and related all matters to Him. We mentioned that the Ruqyah increases in effectiveness according to the strength of faith of the person who is reciting it and the response of the person to the Ruqyah. No sane, honorable Muslim doctor can deny this fact. However, if any of these qualities is absent, let such a person say whatever falsehood he wishes!
