Conditions & Fundamentals of Hajj and Umrah

Q: My family and I plan to visit Makkah Mukarramah from Riyadh to perform Umrah. In case my wife has her menses before travelling, can we still go to Makkah?

Q:

1. Please explain to me the status of the two rakaats performed after tawaaf – are they mandatory or nafl?

2. If someone did not perform these two raakats immediately, then what should he do? Will they be regarded as qadha?

Q: Can one read the 2 rakaats waajibul tawaaf one time after completing 3 tawaafs?

Q: I live in Oman and I am going for umrah. First I will go to Madinah then I will go to jeddah and last I will go to Makkah for umrah. So from where should I wear the ihram for umrah?

Q: If one performs tawaaf in the time of Fajr or after Asr, then when should one perform the two rakaats Waajibut Tawaaf? Is it permissible for one to perform the two rakaats Waajibut Tawaaf in the time of Fajr and after Asr?

Q: I intend going for umrah. Due to my leg problem, I need to wear a compression sock. The compression sock covers the entire leg. Is it permissible for me to use this sock while in ihraam? 

Q: Is it permissible for a healthy person to perform nafl tawaaf on the electric scooters or wheelchairs available in the Haram, even though he is healthy enough to perform the tawaaf while walking? 

Q: Is there any penalty for holding the ghilaaf of the Ka'bah during tawaaf of umrah, or tawaaf in general? Also given the fact that it is perfumed, is there any penalty that one must pay for after holding the ghilaaf, because its itr came onto the person. 

Q: Can the two rakaats after tawaaf be performed outside the Haram Shareef? 

Q: If one goes for umrah or hajj, and during the journey, his ihraam clothing becomes soiled, can he change into a clean ihraam, or is it necessary for him to continue using the same ihraam while merely washing the soiled area?
