Hajj & Umrah

Q: How many umrahs is a person allowed to perform in one day?

Q: A woman washes some clothes and sets out for umrah and enters into ihram. 

Whilst in the state of ihram, will it be permitted for her to wear these newly washed clothes despite some of the fragrance of the washing detergent remaining in them?

Q: My hair is very thin, especially my beard hair. If I make wudhu and do khilaal, then sometimes, few hairs fall off. 

I'm planning to do umrah inshallah. My question is that if I am in the state of ihraam and hair falls off accidentally while making wudhu etc., not on purpose, then will there be damm or anything necessary?

Q: Years ago I made umrah and then I made an overnight visit to Taif. Was I suppose to perform another umrah on my return to Makkah?

Q: Can one perform Umrah with one of those umbrellas that has an elasticated band and you can wear it on your head leaving your hands free... especially when the temperature exceeds 30+ degrees?

Q: If a person has shaved his hair after doing first Umrah and he does another Umrah after one or two days, he doesn't have any hair or the hair is little, it has been mentioned in kitaab that he should use a blunt razor blade on top the head to come out of Ihram. 

My question is that if a person can't find a blunt razor blade will it be permissible to use a hair trimmer on top of the head to come out of Ihram?

Q: If a person is in Hajj with his ihraam on and his friend back in South Africa phones him requesting to borrow his hunting rifle to hunt with, will it be permissible for him to lend the rifle to his friend?

Q: Is it permissible to separate tawaf rounds due to pain? 

Example, I did a few rounds of tawaf one day and a few another day until the seven rounds of tawaf have been completed? 

In the above mentioned situation, if a person is unable to do complete seven rounds of tawaf walking in one go due to pain but can do it separately like the above mentioned situation, will it be permissible for him to do complete seven rounds of tawaf in a wheelchair?

Q: If a woman experiences haidh in Madeenah a day before leaving for Makkah, how should she continue her Umrah and what is the masaa'il regarding donning her ihram and performing Umrah?

Q: When does one go into ihraam? Is it when you perform the 2 rakaats of salaah or when you read the Labaik?
