Removing najaasat

Q: 

  1. My question is that after intercourse I wipe myself. If some sperm gets on my hand I wipe it with a tissue then put my qamees on. Is my qamees paak or do I have to wash my hands before touching anything.
  2. If something is najis. Do you have to wash it 3 times and squeeze each time or until there is no sign of najasaat?

Changing one's zakaat date

Q: I have always had my Zakaat anniversary as the 15 of Ramadaan. If I wish to change this date is it possible? Let's say I wish to from next year change my year to 15 Shabaan. I will do all my calculation on that date and give Zakaat at 2.5%. Is this possible? Alternatively, if the date I wish to use in future is 15 Shawaal, how would I put this into effect? Bearing in mind that this will then make it a 13 month year.

Faking a degree and getting someone else to submit one's papers

Q:

  1. I have done 3 years Diploma in Electrical and have experience overseas. Now I moved to a developed country and started working as an electrician. If you have extensive experience you can work as an engineer. But you still need qualification to go to high in rank and good pay. So is it possible to make a fake bachelor degree and on that fake degree if I get admission in university in Master Program is that allowed in Islam?
  2. Now I am doing masters from university and going on Hajj this year Insha Allah. Now that hajj is coming in the middle of my semester is it allowed that my friend do the remaining assignments on my behalf and submit it? According to university rules nobody can submit on someone elses behalf.

Please guide me.
