Hajj & Umrah

Q: Do we have to drink zam zam water standing up facing qibla?

Q: If a person lives in the premises of the meeqat like Jeddah then is it obligatory for them to do tawaaf of the kaaba on every visit if not in ihraam? If they go for jumua salah then they have to do tawaf or they can go only for salaah? I heard that it is the right of kaaba that if one visits it one should do tawaaf. 

Q: Tell me the best day to perform Umrah? Is it only Thursday nights and Fridays?

Q: Can one wear sandals while making sa'i of saffa and marwah. Also can one use toothpaste in the state of ihram and what should one do if one has a problem with urine drops when in ihraam?

Q: I once performed umrah when I just became baaligh. My grandparents and I entered Makkah without being in Ihraam and also I did not wear proper shoes in Ihraam. However, all of this was done unknowingly, as I had not yet been taught that. Should I still pay a dam and what should one do if one cannot afford a dam?

Q: If any hair from my head falls out unintentionally in ihram will dum be wajib?

Q: My parents and I are going for Umrah on the 23 February insha allah. Please can you shed some light on Umrah for me as this is going to be our first trip out of South Africa. I have been reading books on Umrah.

Q:

1. I have witnessed many Muslims standing up when they drink Zam Zam Water. Those who sit and drink are being ridiculed by many people and even Mullahs who justify that we must always stand up while drinking Zam Zam Water. 
2. I have also witnessed many people standing/walking while drinking water and eating dates in Haram Sharief in Makkah. But, the Sunnah of Rasul Allah Sallallaahu Alaihiwa Sallam is that we must always sit while drinking or eating. Please clarify in detail.

Q: I live in Jeddah. My mother is coming to visit us. She is coming to Madina and next week we are planning to perform umrah with her. Is it a must that she wear Ihraam from Pakistan? Although we planning to go for umrah next week?

Q: I have a question about Umrah. I am scheduled to travel for umrah in early Feb 14 and thinking about going to Madinah first after landing at Jeddah from NY and after staying few days in Madinah, I will travel to Makkah for Umrah. Can I do this or I have to perform umrah first before going to Madinah?
