Selling a waqf property

Q: A plot was given as waqf for the purpose of construction of a school to a masjid trust. There was no agreement in writing or any conditions attached to the grant except that the plot be utilised for education of Muslims. Up to now, it has been more than 12 years since the plot was given but for various reasons the purpose hasn't been accomplished and the plot has been lying idle and become a dump yard for the neighbours.

For this reason, we as donors, asked the masjid committee to release the plot to us so we could carry out the educational development ourselves.

The committee initially expected us to pay part value of the plot for it to be released to us. However on advice of some ulamaa, they have agreed to release it to us without monetary payment.

Since we now have to raise funds to build a school over and above the plot donation, is it permissible for us to divide the waqf plot into two and buy or sell half of it to raise funds to build the school?

Taubah for a music producer

Q: I used to produce music and instrumentals but alhamdulillah I have repented from both listening to and making music. I am worried about the songs I released before, should I worry about them and try to get them deleted or am I free from it since I repented?

I also produced the background music for a podcast/show. I have sincerely repented from making any more music or sending/promoting my music. I feel absolutely horrible and I hope that this spread of my music doesn't come for me in my grave.

Girl choosing to get married or study online

Q: A proposal has come for me but my parents are not calling them so that they can come to our home. They are waiting for their call. Meanwhile, they are signing me up for an online university. As I’m unmarried, I have alot of thoughts about marriage and I cannot stop thinking about it to the point that any mention of marriage makes me feel sad that I’m not part of this union with someone.

What should I pray to Allah (Subhanahu wa Ta’ala) for? For the best solution, whether it is marriage or studying online, or should I beg Him for a good spouse?
