You need to repent to every act.

If a Muslim does any major kufr, later he realized that and he does tauba, will his all previous sins be forgiven including this kufr and all haram acts due to this tauba or does he need to do tauba for every individual haram acts he did?

I go to university in America and professors have a syllabus for their classes. In it there are rules for the class. For example, it may state in the syllabus that google searching for answers to a test is prohibited. However, I don’t think I ever signed to agree to these rules, do I have to abide by them? What if I did want to google search the answers to a test?

When I was walking in the street I saw a paper that had Allah’s name on it but I didn’t pick it up. I didn’t mean to disrespect Allah’s name and I hated that it was on the floor, but I left it there. Is this kufr?
