Relationship with one's father after divorce

Q: I have a very complicated question for you. Basically, my mother got divorced from my father many years ago, it was a forced marriage and was not built to last of course. Father was 40 years older than her, she was just 16 when she got married. Now she is saying I cannot speak to him, nor attend his funeral if he dies. In fact this year she has told me to completely sever all relations with him, otherwise she will disown me. I know she has been through hell and back because of him, and they did not get on well with one another, but do I have any rights, or must I be obedient and do sabr? If mother finds out that I have even glanced at him, I will be disowned and possibly thrown out of the house. I don't blame either of them. I love them both, but why must I go through all this? Is this a punishment for my sins? Your help would be greatly appreciated.

Satr area becoming exposed while making tawaaf in ihraam

Q: When wearing the ihraam cloth and making tawaf around the ka'bah, I am afraid that part of my awrah (just below the navel) will be visible at times, especially when flipping the cloth to the idhtibaa' position etc, since I am not used to wearing this cloth. If my awrah shows, will the tawaf still be valid. Will I have to pay any compensation for it?
