Hajj & Umrah

Q: I know that tawaafe wida is obligatory for hajj. What is the status of it for umrah? 

I've heard some say it is "not prescribed"... Does this mean it is haraam or makrooh or just not compulsory?

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?

Q: During the last Hajj, me and my mother went to Muzdalifah and performed Maghrib and Isha salah. Then our group leader told us to leave Muzdalifah as it was very crowded and he thought there will a lot of delay in getting the transportation back to Mina. So we left Muzdalifah before Subah Sadiqh. Is Damm wajib on me and my mother? 

Q: A person is traveling to Jeddah and wants to go to Madinah 1st when he lands. Then: 

1. Is it fine for him not to be in a state of Ihraam when he enters Jeddah? 

2. Is their any problem in him doing this? Like not preferable etc.?

Q: Can a person make umrah for a living person?

Q: There are people who throw umbrellas, water bottles, shoes, etc. at the jamaraat. Please comment on this practice. Some say "Masha Allah" and praise those who do so.

Q: I had istihadha but not a mazoor. I placed cotton wool like a khursuf but only after completing my umrah and coming out of Ihraam I saw that it messed through. What will I do?

Q: There is a couple that recently came from hajj. They did all things correct but they have 1 doubt. 

After coming from Muzdalifah, doing 1st rami, and cutting of hairs/halaq, they opened their ihram and after that they thought they are open from ihram and out of ignorance and oversight they did sexual relations just before tawaf e ziarat. 

Tawaf e ziarat was done after gusal and proper clean cloths? Would they be required to give damm? If yes, will it be for both or just 1?
