It is permissible to pay zakaah from something other than the saved money?
Question

                Must zakaah be paid from the money that is stored after the year has passed, or can zakaah be paid from other income?.
Praise be to Allah.Whoever has 
    wealth on which zakaah must be paid does not have to pay it from the stored 
    wealth itself, rather he can pay it from other wealth. 
Al-Nawawi 
    (may Allaah have mercy on him) narrated in al-Majmoo’ (5/346) that 
    the scholars were unanimously agreed that it is permissible to pay zakaah 
    from wealth other than the wealth on which it is due. 
And Allaah 
    knows best.
