He bought some land in order to sell it after a while – how should he pay zakaah on it?
Question

                How should zakaah be paid on land which was bought with the aim of leaving it for a while then selling it?.
Praise be to Allah.
    If a person has bought land with the intention of selling it 
    after a while, one of the following two scenarios must apply: 

    1 – He aims to save the money so that he will not spend it on 
    anything else, but he does not intend to trade or make a profit. In this 
    case there is no zakaah on the land. 

    See question no. 34802 

    2 – He does intend to trade and make a profit, in which case 
    this land comes under the heading of trade goods, so zakaah must be paid on 
    it. 

    The value of trade goods should be worked out at the end of 
    one year on the basis of their current value, not the price for which they 
    were bought, and the zakaah must be paid on them. The rate of zakaah that 
    must be paid is one-quarter of one-tenth, i.e., 2.5%. 

    For example: if you bought land for one hundred thousand 
    riyals, and when zakaah becomes due on it its value is now one hundred and 
    fifty thousand riyals, then when one year had passed you must pay the zakaah 
    of one hundred and fifty thousand riyals. The converse also applies. If you 
    bought it for one hundred thousand riyals and when one year has passed its 
    value is now only fifty thousand riyals, then you only have to pay zakaah on 
    fifty thousand riyals. 

    See Fataawa al-Lajnah al-Daa’imah, 9/334; Fataawa 
    wa Rasaa’il al-Shaykh Ibn ‘Uthaymeen, 18/205, 236 

    Note: 
It should be noted that 
    the year for reckoning zakaah on trade goods does not begin from the time 
    one bought the land or other product, rather it begins from the time when 
    the wealth with which you bought those goods reached the nisaab (minimum 
    threshold).

     Based on this, the year for this land is the year for the 
    money with which you bought it.
