I'm not Muslim. It's a good question, tho. I will share what I know; but I'm not sure that it will be credible without confirmation from another Muslim.
Here's what I did. I sent my answer to a friend for proof reading and feedback... and turns out I did pretty good with my answer. Here it is:
Question: How important is Gods authority?
Answer: Very important. a 9 out of 10. Islam technically translates to Surrender. Surrendering oneself voluntarily to Allah's authority is very important.
Question: How important is Gods power?
Answer: Gut response... it's a 4 out of 10. Allah is Omnipotent, but grants freewill and wants us, humans, to grow and experience failures and successes. If Allah is demonstrating Omnipotence all the time then that would interfere with freewill.
Question: How important is Gods Judgement compared to God's Mercy?
Answer: Judgement is a 9 out of 10. Mercy is a 10 out of 10. Mercy is always supposed to win. But the two are connected. You can't have Mercy without Judgement.
Mercy without Judgement is a free-pass.
