Conditions & Fundamentals of Hajj and Umrah

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: 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: This year while performing hajj, the Saudi Government directed the pilgrims to start performing the 12th dhul hijja rami after Fajr due to excessive heat and overcrowding to avoid any untoward situation. So, we performed the rami before zawal on 12th dhul hijja. 

Is my hajj acceptable or do I need to perform anything to compensate for performing rami before zawal? Are there any rulings or views of scholars on performing rami before zawal?

Q: While in a state of Haidh, it is makrooh to remove unwanted hair/nails. However, I will also be entering into ihram during Haidh. Can I shave/trim nails when tying ihram? Is there any sin for having not shaved or long nails during ihram?

Q: My wife and I went for hajj alhamdulilah. We completed our umrah and waited for the hajj days. The morning of the hajj day, very early, because my wife was pregnant and it was the 8 month of her pregnancy so after advise from prominent ulama they suggested I do the saee for the tawaaf e ziyaraah before the hajj starts. So the morning my wife and I did a nafl tawaaf and with the intention of saee for my wife I joined her to do the saee. In this way we completed the saee and then joined up Ml Olgaa to to do our hajj. 

After 5 days of hajj we stayed one extra day in Mina. The next day we came to Makkah and did our tawaaf ziyaraah and my wife did not do the saee as we, according to the advise, she did it before the hajj days, actually the morning before the hajj started. Please advise if this is correct.
