Q: Is day trading in cryptocurrencies halal? Day trading basically means buying and selling your shares within a day. Note, I have knowledge concerning this subject and for me it is not like gambling. What I do (and almost everyone else does) is checking the chart and based on the chart's movements, I make a decision whether or not it could be a good trade. However, what made me doubt the legitimacy was gharar and maysir. I have done so much research about these terms and it still remains kind of unclear whether it is a form of gharar and/or maysir.

Q: I am an intern doctor. We get many samples of medicine from different pharmaceuticals companies. They gives us the sample and describe about the ingredients, benificial ratio for patient and we also can learn of newer generations of medicine which is available now in our country. The packet of samples contain only few medicines e.g.: 2/3 tablets, 1 injection, etc. Because its only a physician sample and over the packet it's written that "physician's  sample, not for sale".

Now my question is, 'Is it halal to sell this sample and use the money for myself'? Many interns sells this product at 40-50% less than the market price. If it is not halal then can I sell and give the money to an orphan child?

Q: As a Muslim doctor working in the emergency department, I come across women frequently requesting the morning after pill. I refuse to prescribe the morning after pill on religious and moral grounds. In that case, another doctor prescribes it. The morning after pill prevents a fertilized egg from attaching to the uterus. It has the potential to become a human. Is it okay to prescribe it if it is based on need, weakness or illness?
