Atheists can say God surrendered his power and authority to evil people. In a way they are right.
well thats because they are atheist. So next time you want to blame Allah too when you commit a sin? Your fake history is a mess, how can an infallible who suppose to uphold Islamic values gave up power and legitimise a person who you believe was against Islam. You zombie always doesnt make sense.
Imams are just instruments of God. Even Israelites who were disobeying Moses knew Moses could by himself take on everyone in a country with God's permission and help.....
But Moses and Aaron didn't, but rather separated from the people and left them for 40 years.
The question is legitimate, when a person given knowledge from God's book can bring a whole throne in a twinkle of an eye, yes it's true Ali could have killed every disbeliever that faced him.
He could have resisted and destroyed waves and waves of people, as well, the believers with him could have been helped by Angels as well and they could have come out victorious like Talut and believers who followed him came out victorious.
Why did God let Yahya get killed when he took leadership and was of the successors of Moses who God protected and provided help against Pharah and his army?
These are legitimate questions.
Why did any Prophets from Bani-Israel get killed, was God powerless to protect them?
Why weren't they all victorious with whatever numbers they had like Talut and his followers?
You see, you can't just plug your analysis of what God and his representatives should do.
When you have immense power that you can split the moon and yet the earth remains and everything remains intact, this is not a human that you can truly over power.
If they give up power, they give up due to wisdom. And if they take it, it's by God's will and permission.
Their lives and deaths are for God.
We can try to understand what they do, but at the end, when Yusuf framed his brothers, it was not that framing is halal for us to do or anything, and there is a lot of actions we cannot easily understand.
But fighting is not always best, and power is not as important as people make it out to be.
If it was as important as people make it out to be, be sure God would never have ever let a Pharaoh rule or oppressor rule.
It's an evil and a heavy trial, but life goes on, and wisdom still can be found, and the true Kings continue to be true kings and rule humanity because in all that, God is the King.
