Q: As a Muslim doctor working in the emergency department, I frequently come across women requesting the morning after pill.

Q: I want to sell physical health eBooks that may contain images of humans for the purposes of demonstration. E.g. a fitness eBook demontrating how to perform an exercise or movement. The intention is that buyers will be purchasing the eBook for the information and content and not for the images. What is the ruling on this (both male and female images, would awrah need to be covered as this is solely for demonstrational/educational purposes?) and will income gained from this be halal? If this is not permissible, could you give me guidance on other methods I can use to demonstrate things such as exercises/stretches with visuals etc.
