Tahaarat

Q: If one’s limb is dry after making wudhu and one is unsure if the whole feet or face was washed and one read salaah with that wudhu, does the salaah need to be repeated?

Q: My wife has nail polish with artificial nails. After we had relations, she wanted to make ghusl, but the nail polish and artificial nails are not easy to remove. It may harm her natural nails. We are on a journey and it is not easy to get removing facilities. Without removing the nail polish, is it permissible to make ghusl or not?

Q: Does my ghusl break when a lizard falls on any body part?

Q: As we all know that almost all houses have lizards. My question is: 

1. Lizard's dropping is found on the wall and it has dried. If we paint the wall and the brush touches the impurity, does it make all the wall with new paint impure? 

2. If this wall with new paint dries and someone with wet hand touches it, but the traces of color is not visible, will his hand be pure?

Q: What should we use in place of cream, bath soap, shampoo and deodorant?

Q: I consider myself a mazoor (excused person) due to chronic vaginal discharge. Nothing excessive but I have leaks especially during prayer. I wear panty liners to absorb the discharge. Sometimes theres a lot or just a few drops or even none (between prayer times). Example due to work I pray Zuhr at the end about 10 minutes before Asr. I still do a new wudu for Asr even though the time is very close. I do a new ablution for each prayer.

My question is, do I have to change the panty liner for each prayer? Or can I keep wearing the same one for 2 or 3 prayers?

Q: Does inserting a tampon break ones wudhu?

If I am a major due to istihadha, and I insert a tampon before wudhu then wear khufain, is masah on the khufain valid for the entire salaah duration or do I have to remove it and wash feet each salaah time?

Q: Many women say that they only wet the scalp of the hair after relations due to the hadeeth of Sayyidah Ayesha (radhiyallahu anha). Is this correct? 

Q: Before becoming a Muslim I made some tattoos on my body. Will my wudhu be valid with the tattoos and is it necessary for me to try to remove it? Removing tattoos can be very painful and laser treatment is very expensive.

Q: I use vaseline on my skin when it gets dry. Will my wudhu be valid if I perform wudhu without removing the vaseline?
