Ruling on selling drugs to non-Muslims
Question

                Is it permissible to sell drugs to the non-muslims (or others) if that is the only way to keep alive? for example as it is s happening to the poor people in Afghanistan?.
Praise be to Allah.
    Drugs are regarded as being among the most dangerous things 
    that those who follow haraam desires can consume, because of the various 
    diseases that may result from them, in addition to what they lead to of 
    promiscuity, moral corruption, spread of immorality and crimes in society. 
    Moreover, the spread of drugs in non-Muslim societies leads to drugs of 
    various types being spread by bad and corrupt people to Muslim countries, 
    which leads to chronic problems, whether in the form of spiritual or 
    physical diseases. So this evil must be prevented and fought by all means. 

    Claims of necessity in such cases should be paid no heed. 
    Rather if a Muslim has no other choice, it is permissible for him to eat 
    dead meat, but it is not permissible for him to sell drugs. There is no real 
    case of necessity that makes it permissible for a Muslim to sell drugs. The 
    questioner’s saying “if that is the only way to keep alive” is clearly an 
    exaggeration. 

    If he plants drug-producing plants in the ground to sell them 
    and deal in them, he could just as well plant permissible plants, and eat 
    from them and sell the surplus harvest. 

    Granting concessions in such cases opens the door to a great 
    deal of evil and promotes the spread of this corruption. 

    Abu Dawood (3488) narrated from Ibn ‘Abbaas (may Allaah be 
    pleased with him) that the Prophet  (peace and blessings of Allaah be 
    upon him) said: “When Allaah forbids the consumption of a thing to some 
    people He also forbids its price to them.” Classed as saheeh by al-Albaani 
    in Saheeh al-Jaami’ (5107). 

    Muslim (1579) narrated from Ibn ‘Abbaas that the Messenger of 
    Allaah  (peace and blessings of Allaah be upon him) said: “The One Who 
    has forbidden drinking it has also forbidden selling it.” 

    And it was narrated from Jaabir ibn ‘Abd-Allaah (may Allaah 
    be pleased with him) that he heard the Messenger of Allaah  (peace and 
    blessings of Allaah be upon him) say, during the year of the Conquest when 
    he was in Makkah: “Allaah and His Messenger have forbidden the sale of 
    alcohol, dead meat, pork and idols.” Agreed upon. 

    Al-Haafiz Ibn Rajab al-Hanbali (may Allaah have mercy on him) 
    said: 

    Whatever Allaah has forbidden the use of, He also forbids 
    selling it and consuming its price, as is clearly stated in the report 
    quoted above: “When Allaah forbids a thing he also forbids its price.” These 
    words are general in meaning and comprehensive, and apply to everything the 
    use of which is haraam. End quote.  

    Jaami’ al-‘Uloom wa’l-Hukam 
    (415). 

    And Ibn Hazm (may Allaah have mercy on him) said: 

    It is not permissible to sell alcohol, whether to a believer 
    or a disbeliever. End quote. 

    Al-Muhalla (7/356). 

    Ibn al-Qayyim said in Zaad al-Ma’aad (5/763): 

    If it is asked: Will you deem it permissible for a Muslim to 
    sell alcohol and pork to a dhimmi because the dhimmi believes them to be 
    permissible? The answer is: That is not permissible, and its price is 
    haraam. End quote. 

    Ibn Jizzi said: 

    It is not permissible for a Muslim to sell alcohol to a 
    Muslim or to a kaafir. End quote. 

    Al-Qawaaneen al-Fiqhiyyah (p. 
    117) 

    Al-Nawawi said: 

    Selling alcohol is invalid whether it is sold to a Muslim or 
    to a dhimmi, or one dhimmi sells it to another, or the Muslim delegates a 
    dhimmi to sell it for him. All of that is indubitably invalid, in our view. 
    End quote. 

    Al-Majmoo’ (9/271). 

    It says in Fataawa al-Lajnah al-Daa’imah (13/49): 

    It is not permissible to deal in that which Allaah has 
    forbidden of food and other things, such as alcohol and pork, even with the 
    kaafirs, because it is proven that the Prophet  (peace and blessings of 
    Allaah be upon him) said: “When Allaah forbids a thing, He forbids its 
    price. And because he  (peace and blessings of Allaah be upon him) 
    cursed alcohol and the one who drinks it, the one who sells it, the one who 
    buys it, the one who carries it, the one to whom it is carried, the one who 
    consumes its price, the one who presses it and the one for whom it is 
    pressed. End quote.  

    These are comments of the Muslim scholars concerning the 
    prohibition on selling alcohol, even if it is sold to non-Muslims, based on 
    the evidence of the proven ahaadeeth from the Prophet  (peace and 
    blessings of Allaah be upon him) concerning that. 

    And Allaah knows best.
