From looking at the specs via gsmarena.com/samsung_galaxy_a51 it does not list wireless charging as a feature and just advises "Fast charging 15W".
Other internet sites also seem to support that this phone does not have wireless charging available @PEGASUS01
Please do consider conducting a Google Search and you'll find these sites.
One option is to either pop.it on a charging pad or look in the settings - Device Care - Tap on Battery - Tap on charging and look for....
Your Samsung Support department or Samsung Experience Store if available where you live can confirm.
There are options to add wireless charging to one such option is available via 》mobilefun.co.uk/blog/2020/02/how-to-add-wireless-charging-to-the-samsung-galaxy-a51
Other options maybe available.

The advice I offer is my own and does not represent Samsung’s position.
I have no affiliation with Samsung.
Hello. I have a receiver mounted on my XA1 it works very well with my charger and in my car (charging system integrated in my seat leon).
I bought an A51 I mounted the receiver, but no charge, yet the charger detects the system (green light) but no charge on the phone.
I also tried my USB-C magnet adapter but same problem no charge. I am really disappointed.
Actually, I just purchased a "Olixar Samsung Galaxy A51 10W Wireless Charging Stand With Cooling Fan" says right in the name that it supports wireless charging. Also my boss has a wireless charger on his desk that works with the A51 as well. I'm going to find out what brand and model that wireless charger is and will post back here as well just in case anybody else comes across this post. I will also let everyone know when I get the charger if it works as expected also.
