Q: Is it permissible to use permanent hair dye? Does it allow water to sink into the skin or does it just sit on the hair like a coating? Also if the hair dye contains alcohol, can I use it and then wash it out?

Q: I want to ask a question regarding hair removal from  private areas. Can I know if we can extend time due to dryness, pimples, or rashes, etc? If we do extend the time of hair removing during this condition, will it be haraam?

Q: I require the following clarifications regarding wearing a Topi.

1. Did Rasul Allah Sallallaahu Alaihiwa Sallam and the Sahaabah Radhi Allahu ​Anhum nurture the habit of wearing Topi during their lifetime? Sahih Bukhari 275 mentions of an occasion when Rasul Allah Sallallaahu Alaihiwa Sallam led the Jamaath having just completed his Ghusl with water dripping from his hair. Similarly other references that Rasul Allah Sallallaahu Alaihiwa Sallam did not wear Topi are mentioned in ​Nasa'i -5219, 4980,  Muslim - 4666, 4680, 4270 Bukhari - 3548, 352, 353 and Abu Dawood - 592, 3658.
2. Did not this practise actually originate in Turkey when it became the capital of the Islamic empire, whose citizens had a traditional habit of wearing the tall and round Topi?
3. Why do Muslims in many countries offer Salaah without the Topi? Are they going against the Deen? Is their Salaah not valid? 
4. Then why do not Muslims who go on Haj/Umrah not wear a Topi (covering their head) by un-stitched cloth like they wear for Ihram?
5. So, going by the above Sahih Hadith, is it still mandatory to wear the Topi ? Is it not a Bid'ah?

Q: Is it true that it is sunnah for a woman to wear some form of jewellery, specifically bangles on her wrists whilst preparing meals for her family?
