Is it permissible for him to sell political books and plays?
Question

                I have a number of non-religious books, including books on politics, economics and history, and a number of novels and plays, both Arabic and international. Is it permissible to sell these books and use the money to buy religious books, or to do good deeds and give charity?.
Praise be to Allah.
    The basic principle concerning selling is that it is 
    permissible because Allaah says (interpretation of the meaning): 

    “Allaah has permitted 
    trading and forbidden Ribaa”

    [al-Baqarah 2:275]
al-Jassaas said: This is 
    general in meaning and indicates that all transactions are permissible. 

    Ahkaam al-Qur’aan, 2/189 
This is as far as the 
    general principle is concerned. But if the item sold is haraam, or if it is 
    usually used for haraam purposes, then it is not permissible to deal in it, 
    either buying or selling. Based on that, one of the following must apply to 
    these books that are mentioned in your question: 

    Either they are useful books which will be of benefit to the 
    reader even if they are not about religious topics, such as history, 
    politics, physics, computer science, etc and do not include – as far as you 
    know – anything haraam, such as lies or promotion of evil or anything that 
    would deceive and mislead people. These come under the principle mentioned 
    above, which is that it is permissible to sell them according to sharee’ah. 
    If it is permissible to sell them then it is halaal for you to use the money 
    you get for your spiritual and worldly interests. 

    Or they are books that are haraam in and of themselves and 
    are harmful to the reader because they include lies, distortions of the 
    facts and of religious truths, corruption of morals, religious commitment 
    and beliefs, or changing the meaning of modesty in women and chivalry in men 
    – as is the case with most novels and plays, whether Arabic or foreign. It 
    is haraam to sell these kinds of books; rather they must be destroyed and it 
    is not permissible to make use of the price, because the Prophet  (peace 
    and blessings of Allaah be upon him) said: “When Allaah forbids a thing to 
    people, He also forbids its price.” Narrated by Ahmad, 2956; classed as 
    saheeh by al-Albaani in Ghaayat al-Maraam, 318. 
And Allaah knows 
    best.
