I'm still confused as to the first two - don't they mean the same thing?
I normally set out my essays like
1. Explain the principle teaching eg human beings are created in the best composition
2. Sources and example (eg euthanasia)
3. Significance for community/individual
I'm struggling to connect individual teachings to the issues I've looked at (euthanasia & abortion). Which issues do you think best relate to each teaching?
The first one is saying: Allah created all humans perfectly. So it's talking about the actual physical creation of a human - the physical existence. In Christianity, they say all humans are made in the image of God. It's that same idea - physically, people are made divinely. The second one is about trusting in Allah's plans. So it's less about the physical existence and condition, and more about life's progression and choices. Allah has created people wonderfully (point number one) and has plans for these people that need to be trusted (point number two). Does that make any sense?
Are you struggling to connect the ethical teachings to the issues? Keep in mind - your two contemporary issues where you apply the ethics, don't need to really compliment each other - they can contrast and show different teachings if you like. They don't have to connect exactly, because they will be linked by bringing it back to ethics at all. So for abortion (I think after 120 days since conception it is not permissible? I'm a bit rusty on that), you might say that it contravenes the ethical teaching that Allah has a plan to be trusted. Euthanasia follows the same vein - it is using one's autonomy in a way that doesn't follow Allah's plan (again, ethical teaching number two). You'd relate these to the principal beliefs as much as possible too - Al-Qadr relates most clearly here, in my opinion! And of course, everything relates to Tawhid - the oneness of Allah - Allah's integrity and greatness is always respected in ethical teachings.
Ethics are tricky to understand, you need to break it down. Start with where the teachings come from, then what the teachings are, then link them to the principal beliefs, then talk about how they may guide the adherent, and then, apply them to contemporary issues. You really have to understand it all in that order for it to make sense as a wholesome structure!
