Can any one suggest some books that I may send to someone incarcerated who is presently giving khutbahs that are qutubi in nature and belittling remarks referring to the 'ulaama. This person has very little access to who the real scholars are and guidance on the correct manhaj, he is giving khutbahs unrestrictedly, no 'ilm!
I have read some articles in SPUBS that I can send him, however, I am looking for a books or books that is comprehensive in terms of the dangers of khurooj, and the qutubis and anything that can benefit that can be mailed to him.
