Definitely not. Most ham already has water injected into it prior to selling it (look at the label). Adding more water will severely affect the taste of the meat. It won't loosen or soften the flesh, because brining does the job.
If you are concerned with the ham getting dry while you heat it (most hams are already cooked), I have a couple suggestions. The more important is avoid overheating it. Ham should never be cooked over 350 F; preferably you cook it at 300 F. The second piece of advice is to make a "foil tent" to completely enclose the meat, reducing evaporation and concentrating flavor.
If you want to brown the top, around 15 minutes at the end of cooking, open the tent and raise the rack to a higher place in the over. Watch it carefully.
Here's something that really bugs me. Most people don't know how to use their oven.
For cooking ham, the recommended temperature is 325F (160C).
certainly defrosted thoroughly if frozenif just cold then fineif salty ham place in large pan of water for 12-24 hours before cooking and change water for fresh tap water every 8 hours or so. The salt leaches out of the ham into the water so when you cook the ham the meat is no longer as salty as it could have been.
Pineapples should be added towards the end. Watch the ham cook. When there are about 15 minutes left, slice up your pineapple. Then add them to the ham. If you are using fresh pineapple, it is important not to add the slices to the ham too early. Fresh pineapple contains an enzyme that will cause the ham to turn mushy. Better yet, use canned pineapple, the canning process destroys the enzyme. Also, do not store the leftover ham with the pineapple slices.
