Q: Are we Muslims allowed to attend marriages of non-muslims?

Q: This evening, I was in a shop about to pay for my shopping, when a woman, who seemed to be off her head, came into the shop and began talking away incoherently with the shopkeeper and myself.  She seemed to be on drugs or drunk or something. She had some shopping gathered, and about to pay for it. Amongst her shopping, she had some beer cans (alcohol). As she was talking to me, she kept on touching the back of my left hand with her index finger every now and then, so as to get me to sort of agree with her on what she was going on about, and also as a way of making a point.  It was harmless, but I felt uncomfortable. But just after she had paid for her stuff, one of her beer cans fell out of her bag on the ground, and I picked it up and gave it to her. That was it. I know one shouldn't deal with alcohol in any way, but I went ahead and picked the beer can up (knowing alcohol is haram) for her and handed it to her! Is there any sin on me due to this? And what is the ruling on this sort of thing, i.e helping someone pick up their beer cans/bottles after they had dropped it on the floor?  What can I do to make up for this if anything? How about the woman tapping me on the back of my hand, as a way of emphasising her, incoherent points? What should I do in this case?

Q: Is it haram to pay interest is one is forced to? For example if the government charges you a tax penalty and includes interest in it, is it haram

Q: My question for today is I did ghusul on 18th of May but from 23rd I am spotting blood and despite spotting blood I was still praying and on 26th I was fasting again despite spotting blood. I told one Muslim lady and she told me my fasting is makrooh, so I had to open my fast. I didn't pray on the 26th till 28th but I did ghusul and I am fasting on 29th but in the morning again I spotted blood so I just wanted to know am I allowed to fast and pray despite blood spotting or not?

Q: If a person led salaah intentionally without wudhu many years ago and now cannot tell each musalli because he does not know who they are
individually. How does one make up for this shameless act. The Fear of allah has entered him and it does not give him peace of mind until he knows that he is forgiven and he does not have to worry.
