I say, and with God's success: Anything that is owned by others should not be violated or taken without the owner's permission; because it is a protected property; thus, it is forbidden to infringe upon it, and it must be returned, unless the owner has permitted it and waived their right. You must return the seedling to its owner, and you should only take it if you have their permission without any embarrassment. You must not revert to such behavior again; so as not to fall into what is forbidden, and God knows best.
