Answered by: Moulana Tahsin Alam
When intending to build a masjid, which type of money should be used?
Can I use sadaqah money or should it be lillah?
بِسْمِ اللهِ الرَّحْمنِ الرَّحِيْم
In the name of Allah, the Most Gracious, the Most Merciful.
Any donation is permitted for building a masjid, as long as it is not from the obligatory zakāh money.
Money donated for the purpose of ‘sadaqah’ and ‘lillāh’ are considered donations.
Only Allah knows best
