hajr-e-aswad

Q: I have a few questions regarding Tawaaf:

1. When making استلام بالاشارة must one raise the hands upto the ears (as in Salaah) or in line with the shoulders? Also, does one stretch out the arms (as if touching the Hajar e Aswad) or must one keep the hands in line with the body?

2. Thereafter, when kissing the hands must one kiss the fingers or the palms?

3. When making استلام بالاشارة in which direction must the body face? In this regard is there a difference between the first Istilaam & the subsequent ones?

3. When making استلام بالاشارة during the course of Tawaaf does one stop at the Hajar e Aswad, make Istilaam & thereafter continue walking, or must one make Istilaam while walking?

Q: In Satanism, the devil's presence is represented by a black cube so why is the kabah a black cube?

Also why do Muslims kiss the black stone and treat it like an idol.

Q: During umrah is it jaiz to touch the ghilaaf of the Ka'bah and to kiss the hajr-e-aswad?
