Reading the Bible and other scriptures

Q: I accidentally read a few verses of the Bible, now I read that we are not allowed to read the Books of the other religions because we might disbelieve in what we must believe in and vice versa. So I was stricken with waswasa. I got really confused while reading them, so I said I neither confirm nor deny these verses and also I neither confirm nor deny if these are in the Quran. Now if those verses and whatever’s mentioned in that really in our religion, will I have committed kufr? What should I do? 

Qurbaani slaughter facility selling skins to a tannery

Q: I am assisting the general public in cutting and skinning the sheep as they do not have any facilities as well as many do not know how to make the slaughter. A farmer that collects skins for the tannery is prepared to collect the skins and after it has been sorted and graded at the tannery, they will then pay us some cash value of the skins.

Question: It is a generally understood common practice in South Africa for the public to leave the skins of their qurbani sheep at the slaughter facility as they have no need for it. The owners of the slaughter facility subsequently do as they wish with these skins that were left behind. If a tannery pays cash to them i.e to the owners of the slaughter facility for these skins, Can they donate it to a musjid for renovations ?
