Every Masjid is a house of Allah where Muslims worship Allah in. Helping in building any Masjid is good except places of enemies of Ahlul Bayt (AS) because their Masjids are like Masjid of Dhiraar which was not for Allah but for Shaitan.
We help every Masjid based in Taqwa, and we never help Masjid Dhiraar which is called Masjid but used as a centre against Ahlul Bayt (SS).
Wassalam..
