No this is no Sunnah of the Prophet (sws). As a
principle, the Sunnah is that established practice of the Prophet (sws) which he
sanctioned as religion. Acts which are not done in a religious perspective never
form the Sunnah. In other words, using olive oil or such other acts of the
Prophet (sws) like riding a camel or eating by hand or wearing a turban are
related to the common practice of the society he lived in; for example, he
fought with a sword because wars in that time were fought with swords; he used a
Miswāk stick because this was the common way of cleaning one’s teeth in those
times; no one can say that if today a person uses a gun to fight a war or a
toothpaste to clean one’s teeth, he would not be following the Prophet’s Sunnah.
This of course does not mean that a person cannot adopt these practices; he,
however, should always be clear that these are not Sunnah.
