Salam,

I have few question about my 401k retirement plan here are some details;
My employer contributes 3% of my weekly paycheck into my 401k retirement plan, regardless i contribute in it or not.

Question1, is it permissible for me to take and use this money, thinking as gift or benefit from my employer with 0% contribution of mine?

Question2, also if i contribute 3% of my weekly paycheck (voluntary) into 401k, my employer still contribute 3% of my weekly paycheck, is this condition right to for me to contribute?

Question3, also if i contribute 6% (voluntary) of my weekly paycheck into my 401k, than my employer contributes 9% of my weekly paycheck into 401k. is this condition right for me to contribute too??

Note:

I have no information and not possible to get the information about where they spending my money if i contribute.
But even if i contribute 0% they still contribute 3% of my weekly payckeck into my 401k.

Now which condition is allowed for me according to Quran and Sunnah to contribute or do not contribute, to take advantage of this retirement plan, and is this contributed money is permissible for me to take and use when needed.

If you have any question, you can email me on amadquddos@gmail.com

Thank you.
