I think answering this question is not so easy.
How high will the humidity be in % and how old is the oud? In which humidity levels was it held until now and how long?
High humidity can be dangerous, but I expect above 60%, so the first question is the most important.
Do you have a hard case?

My studio is on the ground floor, on a hillside, the living room is two flights up at street level, and with California wooden construction being what
it is, in the studio the soil is just some wood boards away. This has been a blessing. Ambient humidity in the Bay Area varies wildly, several times from 20-100% just in the last 24 hours, while in the studio it sits around 70-80%. If I take an instrument upstairs it
starts to drift. Overnight the bass strings shift one way, the trebles the other way, a few hours later it goes the other way. It's a minor nuisance
on a guitar. On an oud it's a chore. Normally in the studio wood is very happy. I don't lock up instruments in cases. It's evenness that matters most.
A few months ago we had a very very dry spell and the studio humidity dropped below 60%. I promptly broke 4 strings on a harpsichord pulling it up to
pitch. On the tropical Mexican seashore the oud i brought became unplayable when the soundboard buckled upward. Your rheumatism may not agree, but I
think your instruments will love it down there. Get a little cheap hygrometer. If coming from a different environment, keep the oud in a case at first
so it gradually equilibrates.

the oud is gonna be brand new and handmade.
if i keep it in a soft case will that help to protect it against humidity?

It is impossible to answer your original question.
Most museums will maintain a relative humidity of 55% to preserve wooden artifacts from deterioration due to humidity cycling. However for a new
musical instrument some humidity cycling (within reason!) should be of some advantage in helping to relax any inbuilt stresses and so improve acoustic
performance over time. My instruments are kept in my library (not enclosed in cases where the humid micro climate inside a case could itself be
damaging) and are subject to a relative humidity range of about 50% to 75% without adverse effect - although in the heat of summer at higher humidity
levels the instruments do not respond as well acoustically as at say 60%.
So you should guard against humidity extremes - particularly sustained low humidity conditions that can cause wood shrinkage and cracking of the sound
board.
Presumably you will be living in some comfort in your basement which as a living space should be properly constructed, drained and insulated to code
so you should not have to put up with extreme humidity conditions. Besides basements being below grade should be more protected against extreme
climatic swings than above grade dwellings.
If you have climate control facilities then a humidity meter would be a necessity - otherwise it would be of little use except to determine if the
part of your living space where you plan to keep your oud is a relatively stable environment.
The big unknown is the condition under which the oud was originally constructed and how well it is made. The sound board wood should not only be well
seasoned but should be brought into the workshop environment to stabilise weeks before being used. Hopefully the workshop itself would be climate
controlled to optimum RH but it is questionable if this is generally the case except for instruments made by a few of the better luthiers. Otherwise
it is matter of chance of how well an instrument might stand up to changing environmental conditions (most do however!).
Good luck
