Receiving rental from a house that was purchased with haraam money

Q: My grandparents won a lottery of 1 lakh rs around 20 years ago. They then added some amount to this lottery amount (around 35K rs) and purchased a home. Thereafter, one of my family members lived in that house. Presently that house is on rent and we receive a rent of around 10K rs per month. I came to know that lottery is haram. So what should be done now?

Building an astro turf field on musjid premises

Q: A certain musjid has decided with the approval of a Mufti to build an astro turf soccer field on the musjid premises, whilst the premises is waqf. The project is spearheaded by the main Imaam and a collection drive is on for the funds of approximately R450 000. The organizers feel that they will attract people to the musjid and save them from the evils out there. The usual suspects that are being followed are the Ulemaa and community in a nearby town (apparently the nearby town has a similar facility in their muslim school yard). This astro turf will apparently be open to females asking them to adhere to purdah whilst they make use of the facility. The project seems rushed to beat anyone putting a stop to it.

1) Can such a project be done on waqf land?

2) Can females play sport in the musjid yard?

3) Should the organizers lease the land and pay a fee to the musjid?

Hurmat-e-musaaharat

Q: For hurmat musaaharat to be established, is it necessary that shahwah be felt at the exact time of touching. Now suppose a man touches a female. He did not intend to touch her with desire. But their hands were together for a few times. At this time the man felt lust. That mans, shahwah was not present at the beginning of the touching, but it came when the hands were in contact of each other. Does it establish hurmat musahara?

Marital problems

Q: Me and my husband have been apart for 6 years. He has not supported me and our daughter. I have given him an ultimatum to choose before we got seperated because he was abusing me physically and emotionally and financially. He became violent and started to disrespect my family and me. The Imam of our town said the marriage can be claimed void due to the fact that we have not been in any contact for 6 years and also if we can find out if he converted back to his previous religion. Can you please tell me if it is possible because I want to move on with my life and the Imam is dragging the whole process.
