Impurities

Urine on the bedsheets

Q: My son did urine on the bed and it got dry afterwards. If I sit on that bed then will me and my clothes be impure? If I wash the bedsheets only once,  if I touch the bed sheet wet or dry will I be impure in both cases?

The size of the dirham

Q: I want to know about impurity that is equal to one Dirham. As I am in Pakistan, so tell me the size of the coin here. I have searched a lot but I didn't understand clearly. So please tell me in simple words. Also, I am very disturbed due to semen. Bad thoughts come untimely and some liquid comes out, so that Dirham concept applies here? Because I pray five times a day, I can't take a bath again and again. Please help me.

Cleaning impurity from the table

Q: I just wanted to confirm that If I take soap water and wipe the area with soap water and then wipe it clean with clean water and cloth will it suffice as I cannot wash the table with water. If I will pour water it will fall on floor making floor napaak, so will wiping it with a wet cloth suffice.

Mazi

Q: A woman is newly married. Whenever her husband comes in front of her and even in the same room, she feels very nervous. She feels like butterflies in her stomach and tingly sensation in the private area. Some liquid comes out. She is very confused that is this mani or mazi?
