Tahaarat

Q: There is this book called "The Tablespread Of the Holy Prophet" written by Muhammad Faisal

There is a section on cheese. This hadith is a Sahih Muslim Hadith 687, Narrated by Abu Hurayrah (radhiyallahu anhu).

"Performing ablution in the mosque, he said: I am performing ablution because of having eaten pieces of cheese, for I heard the Messenger of Allah Ta'ala say: Perform ablution (after eating anything) touched by fire."

I would like to know what is meant by "touched by fire" and why should we make wudhu after eating something that is touched by fire?

Q: Some books mention that one should recite Surah Qadr after wudhu. Example Talimul haq, practical salah by Talimi Board.

Q: I travel for work and sometimes my agent takes me around in his vehicle. There are times when his vehicle has some dog hair on the seats and on the floor. By me sitting on the seat, some of the hair may come onto my clothes which I try and remove. Can I read salaah or are my clothes napaak? 

Q: Does earwax in ears prevent water reaching in the ears, or is it ignorable and doesn't prevent validity of ghusl?

Q: After salaah I saw a little dough stuck on my nail. Was my wudhu valid? Do I have to repeat my salaah?

Q: Kuffain made of leather are stitched. Water can seep in and out from the seams where they are stitched. Is it permissible to wear such socks?

Q: A person has a medical condition where water fills in his legs. He has to wear a stocking/sock that is very tight. This sock helps mitigate the condition. It is very difficult to take off and put on the sock.

In this situation, will it be permissible to make masah on these socks in wudhu?

Q: I took a bath after haidh forgetting that there is nail paint on my one nail. What should I do now? Can I peform wudu or should I take a bath again although my hair is wet?

Q: When making wudhu using a mudd, what is the preferred sunnah method, does one throw the water in the palms and then use it for each limb, or can one merely submerge the hand in the utensil and use it that way, after washing the hands first?

Q: Is taking a bath in a bathtub haram? Does it resemble the kuffar or because of the usage of water is too high as compare to taking a bath with a bucket and much or compare to using shower. So will it be israaf?
