I have signed an agreement to purchase a property in the last month of which 90% of my liquid cash will be used. I usually calculate my zakat during the month of Ramadan and make payment during this month.
I wanted to know given my current obligation commitment for funds to be used in the next few months whether these funds should be included as part of my zakat calculation I.e. Added rather than subtracted.
InshaAllah you can revert back as soon as you can.
Whatever portion of committed or promised funds which is still your property and under your control as part of your own wealth, if it has been thus for a full lunar year, is zakatable.
