Spending from Zakah money on completing building the Masjid he vowed to build

Q 1: I vowed that if Allah helped me go on a secondment to Saudi Arabia, I would build a small Masjid (mosque) for Allah's Sake. Praise be to Allah, I succeeded to travel and built the small Masjid. Only some finishing touches are needed such as floor tiles, paints and carpets, is it permissible to spend on this out of my Zakah (obligatory charity) money or not?

A: This is not permissible, for spending on Masjids is not of the Eight Channels of spending Zakah, regardless of whether this is a vow or not. You should spend on the Masjid out of your own money.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
