So my wood is safe to use in my tank?If he bought if from a pet shop for aquarium fish use, then it's safe.
Just make sure its for fish and not for reptiles.
It looks like the Azalea wood or spiderwood.

Luckily its not grape I believe. It looks like either azalea or spider wood... I have couple of fish fry in the tank and coul sacrifice them and couple of shrimp in my spare tank and see if its safe. No other way of knowing. Should I keep the wood in the tank for 2-4 weeks?I cannot say if this wood is or is not safe. If it is Mopani, it should be. If it is grapewood it might or might not be safe--this wood is known to have a toxic fungus in some of it but not all. Azaela is not safe.
Azalea I believe is toxic through and through, and can be used with reptiles but not submersed in an aquarium. I'm not saying this is Azalea, just noting it is toxic wood. The other types tend to have a white fungus/slime that is sometimes toxic and sometimes not. The toxic one is deadly. I had a piece of some branch I bought in a fish store several years ago, and it developed the white fungus/slime, and at the same tie the cories were having real trouble respirating. The water also took on a slight haze something like a bacterial bloom. I knew it must be the wood so out it came and got scrubbed under the hot water tap. Dried it out. Put it in another tank, all seemed OK for a few weeks, then fish began acting odd and I saw that the "fungus" had reappeared on the back side where I didn't see it, so that was it, out it went to the garden. I happened to be in a local fish store around the same time, and overheard a customer relaying a similar story, except he had not realized it was the wood and all his cories literally turned belly-up in a day. Similar reports on various forums.Luckily its not grape I believe. It looks like either azalea or spider wood...
