This piece of land you bought and intend to sell when you determine to marry is classified under commercial commodities, since you intend to sell it when Allah facilitates for you the matter of marriage. Thus, you should estimate its value upon the passage of a Hawl (one lunar year calculated from the time a property reaches the minimum amount upon which Zakah is due) since you bought and intended to sell it. Whatever price (equal to or more than Nisab; the minimum amount on which Zakah is due) it reaches at the time of this estimation, you should pay 2.5% of it as Zakah. Whenever another Hawl passes without you selling it, it should be evaluated and 2.5% of its estimated price should be given out as Zakah. It does not matter whether its current price is less or more than what you paid for purchasing it. The Zakah due on it should be given out in the same currency used in its estimation or in gold or silver. This is in order for you to discharge your responsibility and to be on the safe side and be more precise in estimating its value. (Part No. 8; Page No. 116) Your possessing no other resource for income than your salary, or your remaining jobless for a period of time, has nothing to do with the obligation of Zakah on you. In other words, this is not a justification for exempting you from paying Zakah, since the Zakah here has to do with the land you intended for sale.It is permissible for you to give the Zakah to one of your brothers provided he deserves it, i.e. Being a poor person. In this case, you can give him out of this Zakah due to his poverty and need. There is nothing wrong with this. Rather, giving it to a needy relative is to be given priority and preference. The Prophet (peace be upon him) said:
Your charity to the poor is regarded as one good deed, but paying charity to your relatives is both charity and maintenance of ties of kinship.
Imam Ahmad and
Al-Nasa'y) This is the wording recorded by
Al-Tirmidhy who said: It is a Hasan, Sahih Hadith (a Hadith which according to Al-Tirmidhy stands at a higher level than a mere Hasan Hadith, but at a bit lower level than Sahih).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
