.... I think human brain still can't figure out what actually the purpose of some commands. As long as the commands are good for us and the others we should follow it. But still, as a human we always have to think first before doing something.
my one cent,
Allah knows what we do not know...Allah is Most Merciful...Allah's commands must be good for us...Commands are to be followed ...not some problems to be solved.
Thinking may lead us to the danger zone of agreeing or disagreeing the commands...hence we may obey or disobey Allah.
Of course, we are recommended to use our cognitive power to think...it may good for us if we think about all things found in creations.
How about just putting our trust to Allah.
Obeying Allah's commands, for sure, is more important than having the knowledge (i.e., the purpose of the commands etc.)
If we are allowed to take a lesson in the story of Adam a.s.,
Prophet Adam A.s. lives in Jannah and has only one rule (if we are allowed to count)...do not come near or touch the tree.
Prophet Adam has the knowledge (i.e., the purpose of the commands etc.) yet he still disobeyed the command!
If I am allowed to say it again:
Obeying Allah's commands, for sure, is more important than having the knowledge (i.e., the purpose of the commands etc.)
....I know my knowledge about Islam is just too little and I hope Allah will help me to be a better muslim. Ameen.
You are not alone, akhi... my knowledge about Islam is close to nothing....
I hope Allah will help all Muslims to be a better Muslims. Ameen.
