Impurities

Q: Can we say zikr and salat if we have najaasat (e.g. small amount of urine) on our clothes or body?

Q: If one's lips bled with some of the blood going into the saliva, and the person spat out three or more times, then is it permissible for him to swallow his saliva after that? 

Q: I had an impurity on my hand and it dried. I meant to wash it but I forgot and then I washed a pot (with my hand), heated up something in it and drank it. Is this pot (and what I drank) pure? I washed it under running water. Do I have to worry about the other dishes in the sink being impure since I washed the pot over these dishes (the water I was washing with ran all over them), or can I just assume they are pure?

Q: If one's gums are bleeding a small amount (for example due to brushing their teeth before bed), can they sleep like that and rinse their mouth when they wake up?

Q: I had a question regarding the purity or purification of bed sheets or similar stuff impacted with semen (both visible stains as well as invisible). Please give a detailed and clear idea about the ruling regarding the same. If it is impure then how do I wash large bed sheets, mattresses or blankets in both cases having visible semen stains as well as non visible semen. If I sleep in the same setup do my cloths or body get impure?

Q:

1. If some drops of urine get on the side areas of vagina even after all the precautions, does pouring water over them using Muslim shower during istinja is enough? I usually wash my legs separately, wash with soap and pour water over the area thrice as i don't get satisfied by pouring water while making istinja from Muslim shower. What is the right way? I read on your website somewhere that drops dont need to be washed..they can be wiped with tissues. Is it correct?

2. How many times water should be poured on napaak body part? Some says two, some says three. I use soap then pour water thrice. Is washing with soap necessary?

Q:

If I have preseminal fluid on my skin or underwear.

1. Do I have to change my underwear?

2. Do I have to take a shower?

3. Are my pants/shorts impure?

4. If my shirt touches that part, is it impure?

Q: Please advise with regards to wiping a baby's bottom while the baby is still in diapers. Is it sufficient to use the baby wet wipes, as it removes all visible impurities, or do we need to wash as well?

Q: What is the best way to remove impurity from countertops? I had some wet impurity on a part of the countertop a while ago and it dried and nothing was visible, but the impurity itself was not visible. I spilled some water over a majority of the countertop (I could not cover the entire thing in water, as the water would have spilled over the sides), and then wiped it dry with tissue. The countertop is made of wood with a resin top however some of layers have come of so some wood is visible (the impurity was not on the wood parts, but the water I spilled on the impurity did get to the wood). Is this counter top pure? If not how do I clean it (note that impurity mixed with water has touched most of the countertop and since we make wudu/wash our hands here, no doubt it has transferred to a whole bunch of places). How do I take care of this?

Q: I have a watch which has a genuine leather strap. My question is whether it is permissible to wear such watches because we are not aware of whether the animal used for the leather is halaal and has been slaughtered in the halaal way.
