Permissibility of changing the assigned location of the Masjid if it has many Masjids

Q 2: On his death, my father bequeathed that we should build a Masjid (mosque) on his behalf, hoping that it will draw him closer to Allah (Exalted be He) and that it will be recorded among his good deeds. (Part No. 16; Page No. 342) However, some problems occurred within the family that hindered us from building the Masjid at the time. Now, more than 10 years after the death of my father (may Allah be merciful to him), there are many Masjids around us, in fact in the whole area where my father wanted to build his Masjid. Our house is located on the main road in Biljurashi and within one kilometer, there are 6 Masjids. As a result, only a very few people perform Salah (Prayer) in each Masjid, and at times it is only the Mu’adhin (caller to Prayer), the Imam (the one who leads congregational Prayer), and one or two other people who are praying. This is with the exception of the main Masjid, where there is approximately one row of worshippers in each Salah, other than the Jumu‘ah (Friday) Prayer. My older brother still has the money for the Masjid since our father’s death, but nothing has happened. Is it permissible for us to build the Masjid in another place or contribute to building another Masjid, even if it is outside Saudi Arabia, such as in Afghanistan or any other Muslim country? Please advise us and may Allah reward you with the best!

A: If the place that your father specified for the Masjid to be built is not in need of a Masjid at the present time, build it in another place that needs one in the same country. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
