Musjid

Using the empty space of a waqf property for performing Salaah

Q: A property had been made waqf with the intention that the income be utilised for various charity purposes. Presently there is a dire need for a at least a Musallah where the local Muslim brothers can offer daily 5 salaahs. The waaqif is willing to make a supplementary Deed to incorporate the establishment of a Musallah on the empty terrace of the building he had donated. Is this ok and can one perform Jummah salaah and also tarawih and Eid salaah in addition to the daily 5 times salaah in such a place?

Non-Muslim donating money towards the building of a Musjid

Q:

1) If a non-muslim ( hindu or christian, etc ) gives money towards the building of a mosque, is it acceptable?

2) If the whole project of building a mosque has been financed by a non-muslim, can we pray in such a mosque? Will our prayers be acceptable?

3) If a non-muslim has financed the building of a madrasah, or some classes of that madrasah, is that acceptable? Can our children learn there?

Passing wind in the Musjid

Q: I sat in i'tikaaf this year alhumdulillah. But my question is approximately every 15-20 minutes I needed to past wind (due to digestive problems). It was very hard for me to pray taraweeh and the other salaahs but Alhumdulillah I managed. So will I get sin for passing wind in masjid?
