The Prophet's Ruqyah 'the dust of our land and the saliva of some of us...' referring to some people in particular

Q 1: It is narrated in Sahih Al-Bukhari on the authority of `Aishah (may Allah be pleased with her) that the Prophet (peace be upon him) used to say to the patient: In the Name of Allah, the dust of our land and the saliva of some of us would serve as means whereby our patient will be cured by the Will of Allah. The question is: Does the saying ...With the saliva of some of us... Indicate singling out some people and excluding others? I hope Your Eminence will point out the correct way to apply this Hadith.

A: The Hadith is interpreted according to its apparent meaning. The person performing the Ruqyah (reciting Qur'an and supplications over the sick as a cure) would wet his finger with his saliva and touch the dust with it, then wipe with this finger the place of pain reciting this Du`a' (supplication). (Part No. 1; Page No. 78) The majority of scholars are of the opinion that this way of performing Ruqyah is general in terms of the person who does it and the land where it is done. However, some said that this is particular to the Messenger of Allah (peace be upon him) and the land of Al-Madinah. It seems that the first opinion is the most correct, because there is no evidence that indicates that this way was restricted to the Prophet (peace be upon him). And Allah knows best.
