Zakat on a Flat Booked on Installments

Short answer: It depends on the purpose. (a) For your own residence: no zakat on either the paid installments or the flat — the money paid is no longer yours, and the flat is a personal-use asset. (b) Intended for profitable resale: it is a trade investment — each zakat day pay 2.5% of the market value of your booking/allotment right; unpaid future installments are not your wealth and do not enter the reckoning. Details: Paid installments become the developer's property; what you own is the contractual right. With resale intent, that right is your trade good, valued at what transferring the booking would fetch today. Outstanding installments follow the debt rulings — on the sounder evidence-based view, future liabilities do not block zakat on wealth in hand, though some scholars allow deducting the imminently due installment. Evidence: Sahih al-Bukhari 1 (intentions); Sahih al-Bukhari 1464 (personal-use exemption); Quran 2:267 with the Permanent Committee's real-estate fatwa principles. For complex individual cases, consult a qualified scholar.
