Doubting if one perhaps purchased stolen sugar cane

Q: While passing through one of the farm towns, a guy at the garage was selling avokados in a bag. When I bought that, he offered me suger cane as well. Only after I bought it and returned home, did I realise that he only had one sugercane. So I perhaps thought that why was the avokados in a bag which he had lots of (in different bags), but he only had a single sugercane. I perhaps thought that maybe he got the single sugercane by walking past one of the farms and taking it with out paying for it, which he sold to me. What should I do in this case, if I doubt that the sugercane was perhaps stolen?

Breastfeeding through medication

Q: My wife and I cannot have children however we are considering "adoption" but in the sense of fostering, i.e. ensuring that the child would not take our name and would know of his or her lineage. How I would do that, Allah grant me hikmah and make it easy.

I understand the legal issues around breast-feeding and the mahram status it provides to adoptive muslim "parents". Would this status still apply if my wife were to induce (by means of taking medication) the production of breast milk in her body? That is to say, the breast milk would not be produced by means of a child being born to my wife, but rather due to taking a pill to cause it to breast feed another child. We are both Hanafi.

I understand that this too is a modern phenomena, ie, inducing by means of medication the production of breast milk. Being a modern phenomena, there could probably be ikhtilaaf on this matter. I would like to now what is your opinion on this matter and with great respect, ask you to please explain the proofs for arriving at that opinion. Also if there is another opinion held by other ulema, could you possibly inform me of that opinion and also the proofs they may have.
