Is it permissible to pay zakat on wealth that has reached the nisab and on which a year has passed, and to allocate a portion of this zakat for home renovations that were done to help the family? And is it permissible to disburse zakat at the beginning of the month if the intention is present?

Zakat on wealth becomes obligatory upon reaching the nisab and the passing of a full lunar year (hawl). It has no relation to Ramadan, which is associated with Zakat al-Fitr. If a full year has passed on your wealth, you must repent and seek forgiveness, and disburse the Zakat immediately. Saving money for your trousseau does not exempt you. It is not permissible to give Zakat to a mother because her maintenance is obligatory upon her child, nor is it permissible to give it for home renovations. Zakat must be given to those who are eligible, namely the poor and the needy, and its amount is one-quarter of one-tenth (2.5%) of the wealth upon which a full year has passed.
