Q: Without wudhu is sajda haram?

Q: If someone has applied henna and wants to perform wudhu, should one remove a covering bag and wipe the head, still covered with henna, or can one wipe over the covering itself.

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: Is it necessary to rub the whole body during gusl or it is enough for water to flow over the body?

Q: If someone applies henna on the head and then covers the head with a polythene bag, will it be permissible to do masah on the head during wudhu?

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:

1) I have problem of urinary inconsistence. I have to wait for nearly ten minutes after urinating for the drops to stop dripping. Moreover I am quite certain that drops dribble in my clothes while I am sleeping. I do feel the sensation of urine drops coming out in daily routine also, however the number of occasions this has really happened are very few (once every 20-30 times). In such a scenario, if I have a sensation that a urine drop has dribbled, but I am not in the position of verifying it, then is it OK for me to consider my clothes tahir?

2) If I am able to verify that drops have dribbled and made my clothes najis, should I offer prayer because it is not possible to change clothes or undergarments in office or in travel? If I am at home, I immediately change my clothes and purify myself.

3) Because of urinary inconsistence, my mind is subjected to waswasa every now and then. If I am not tahir (paak), then I usually try not to touch anything. There are many things which I do not touch because I think I have made them najis at some point in the past. I do feel restricted in daily life due to this habit. One solution is to purify these objects, but I cannot do this for all the objects like microwave oven in hostel, table tennis table in office etc. What I should do about these objects?

Q: Do I need to take a bath if someone smokes weed in front of me?

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?
