Q: I have a question which always brings doubt to me with regards to ghusal. This happens to me all the time like this morning when I got back home from fajr I went to use the bathroom and on taking out my underpants I found a tiny dot of wetness and small white marks on my underwear. I then urinated and whilst urine emitted I watched to see if anything odd is emitted, I found that a little of white liquid came out as well which was sticky. Is this mani or mazi? I always get confused and then get waswasas. Do I have to make ghusal or do I just put on clean underpants and make wudhu?

Q: If there is napaaki on multiple spots on the wall, can I just use one cloth and wipe them all off the wall generally or would the napaaki spread all over?

Q: Yesterday my husband sat on a bench at the airport which had crumbs on it. I am not sure what the source of the crumbs are and I am now concerned that everywhere he sat thereafter like the car as well as the bags which came into contact with the parts of his clothes that touched the bench have now become napaak. I did check his clothes for traces of crumbs but it was hard to determine what was crumbs or just fluff and dirt and also what was the source of it as he was wearing the clothes the entire day and could have gotten the crumbs and dirt from various sources. Please let me know if I am required to wash everything that his clothes came into contact with thrice to make it paak?

Q: After I showered, I was walking out and my soaking hair touched the wall where there was napaaki and then I didn't wash it because I don't know if its napaak, is my hair napaak now?

Q: Is ethyl alcohol from corn halal? the reason I wanted to know is because I got a reply from a company who said they use ethyl alcohol from corn in their dish washing liquid, so is this washing up liquid permissible to use, because it is washed off anyway.

Q: If there is dry najasat-e-ghalizah on a wall, will wiping it down once suffice? Also if clean dry clothes were placed on something that had the dry najasat-e-ghalizah on it, will they become napaak?
