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.

Q: A female servant washes clothes in my home. My wife puts both pure and impure clothes in a bucket and adds water and washing powder. Servant washes those clothes on washroom floor with a detergent. She throws the impure water from the bucket and fills that with new water. She does not clean the bucket before filling with new water. She rinses the washed clothes in that water. Again throws water and fills with new water without cleaning the bucket and again rinses clothes for second time. Also she does not squeese the clothes after rinsing. Are these clothes be considerd pure? 

As I have doubts about this method of washing , I wash my clothes seperately. But my wife's wet clothes washed in the above method come in contact with my wet clothes when we place them to dry. If my wife's clothes are considered impure, do my clothes also become impure as my wet clothes come in contact with them.

Q: Sometimes when I go to the bathroom I see a white spot/stain. The thing is that the stain is there when I am awake. I mean that if I don't sleep for a whole day and then see it is there. Even If I don't get aroused there is a spot. It doesn't feel wet and neither does my private part fell sticky or slimy like its covered nether does my skin. This case is when I haven't slept for whole day after changing underwear in morning. I don't even feel anything if it there or while coming out if something does come out

1. Am I impure?

2. Do I have to change my underwear and do I have to do ghusul? 

Q: We have a washerman, who after cleaning the clothes with detergent uses hodees (small water ponds to store water) to wash them completely. He uses 3 or 4 such hodees such that after putting clothes in one, he puts them in the other to remove the remains of the detergent... Will it suffice to make the najis clothes paak if one finds no signs of najasat afterwards...

Q: My husband bought chocolate the other day, the one he bought didn't have alcohol but I noticed some of the chocolates did have alcohol. Since the workers of the shop use one spatula to lift all the chocolates and give it to you, would this make my husband's hands and everything he subsequently touched after touching and eating the chocolate napaak?

Q: I read somewhere that ground, wall made of bricks and trees become tahir (paak) if najasat (on them) becomes dry and there is no trace of it present?

Q: Please explain the logic in this. A lizard fell on my mom, then my grandma told my mom to wash her head, then only can she perform Salah, otherwise it's not permissible, is that correct?
