Does paying more than the amount required for zakaah mean that one is allowed to take interest?
Question

                There seems to be some difference of opinion about interest and whether it is halaal or haraam. 

If I pay more than the amount required for zakaah in Ramadaan or more than the amount of interest, will it become permissible for me to take and dispose of this interest and will it become pure?.
Praise be to Allah.
    Interest from the bank is haraam according to the consensus 
    of reliable scholars. Many statements have been issued to that effect by 
    many respectable academic bodies in the Muslim world, such as the statement 
    issued by the Islamic Research Council of al-Azhar in 1965 CE, which 
    included representatives and delegates from thirty-five Muslim states. In 
    this statement it says:  

    “Interest on all kinds of loans is forbidden riba, regardless 
    of the type of loan, because the texts of the Qur’aan and Sunnah, when taken 
    together, definitively forbid all types.” 

    A statement was also issued by the Islamic Fiqh Council 
    belonging to the Organization of the Islamic Conference, in 1985 CE, in 
    which it says: 

    “Interest on loans in return for deferral of repayment when 
    the borrower is unable to pay them when they are due, and interest on loans 
    from the outset, are both forms of forbidden riba.” 

    A similar statement was also issued by the Islamic Fiqh 
    Council belonging to the Muslim World League in 1986 CE, in which it said: 

    “All wealth that comes by means of riba-based loans is wealth 
    that is haraam according to sharee’ah. It is not permissible for the Muslim 
    to make use of it, whether he deposited the money for himself or for anyone 
    of his dependents, for any of their affairs. He has to dispose of it by 
    giving it to charitable projects that will benefit the Muslims, such as 
    schools, hospitals, etc. This does not come under the heading of charity, 
    rather it comes under the heading of cleansing wealth of haraam elements.” 

    It is not permissible under any circumstances to leave this 
    interest in the riba-based bank to increase. This sin is greater with regard 
    to banks abroad, because they usually support Christian and Jewish 
    interests, thus they use the wealth of the Muslims to further aggression 
    against the Muslims and mislead them from their religion. It should also be 
    noted that it is not permissible to continue to deal with these riba-based 
    banks, whether one deals directly in interest or not.

    Hence we may understand that the confusion that some people 
    try to stir up as to whether interest is haraam or not is something to which 
    no attention should be paid. 

    Interest is impure wealth from which zakaah and charity 
    cannot be given, whether that is zakaat al-fitr in Ramadaan or other kinds 
    of charity. What you have to do is to get rid of this money by donating it 
    to Muslim charitable causes, and also stop dealing with riba based banks as 
    much as you can. 

    And Allaah knows best.
