Conditions & Fundamentals of Hajj and Umrah

Q: Someone went for Umrah and before starting, emptied his bladder as he had the desire for it and then reached Haram Shareef. It was too crowded and he had to walk a long distance to enter Haram as the passages were closed. Now after a while, before starting Umrah, he again had the desire to empty his bladder (though he did not eat or drink for the past 6 hours to avoid this problem). He felt it is difficult to go out to relieve again and started and completed Umrah and during Umrah, Esha jamaat as well. That feeling was off and on. 

Will the Umrah be valid? If not what is to be done, sadaqah or repeating the umrah? 

If umrah was not valid, did he come out of ihram after completing Umrah and performing Halaq? 

He repeated Esha prayer. Was it needed or not?

Q: Myself and my family will be going for umrah in March In Sha Allah. 

I am in niqaab and I wanted to find out the ruling if I can keep my niqaab on and give out a damm as I make pardah from my brother in law's and they are going to be with so I can't take it off completely.

Q: We came on Umrah with kids and my 6 years 8 months old fell too sick that we have to take him to emergency in Mecca in the state of ihram. 

We treated him and then my wife and my daughter we performed Umrah Alhamdulilah. But due to his sickness we can’t take him for umrah and he had to be taken out of ihram state to take rest. What should I do? Is Damm or Sadqah wajib on me?

Q: My wife wants to make tawaf on the mataf and I don't want to because I need to wear the ihraam and go. I was told not to wear the ihraam and go because I will be lying that I am making Umrah and I wouldn't be making umrah. What must I do?

Q: I have difficulty with my knees while walking long distances. 

1. While in the state of ihraam, will it permissible for me to wear a knee guard? 

2. In the state of ihraam, can I wear an ankle guard?

Q: I intend performing Umrah for my deceased parents. I’m travelling to Jeddah and staying for 2 days with my niece who resides there. After I finish Umrah I will go back to Jeddah for a week and then to Doha for 2 days. 

When and where do I don Ihraam? 

Can I perform 1 umrah for both my parents?

Q: With regards to Tawaaf, when making Istilaam (besides the 1st and last Istilaam) while making the remainder of the Istilaams in between: 

1. Does a person stop and face the Hajre Aswad with his entire body face and chest? 

2. Does he raise both hands or one only?

Q: Is it Mustahabb to recite Durood Shareef whenever a person recites Talbiyah?
