Actually that what we call in Islam Jihad Alkalema (i.e, Jihad using your tongue).
Here are Quran & Hadith supporting that type of Jihad:
“
Therefore listen not to the Unbelievers, but strive against them with the utmost strenuousness, with the (Qur-an).”
(Quran 25:52).
Sahih Muslim, Book 001, Number 0079:
“…I heard the Messenger of Allah as saying: He who amongst you sees something abominable should modify it with the help of his hand; and if he has not strength enough to do it, then he should do it with his tongue, and if he has not strength enough to do it, (even) then he should (abhor it) from his heart, and that is the least of faith.”
