Is ligation permissible?

Q: I am 36 weeks pregnant with my 5th child. This baby and 4th baby were unplanned. I delivered a child one and half years ago with a c section and now again it will be a c section. It will be my third c section and its getting tough for me. I have searched online a lot and found out that tubal ligation is haraam. Unless the mothers health and life is at risk. Of course if I get pregnant again very soon, my health is going to suffer and I don't want to bear the pain of another c section again. So I just want your opinion if I can go for ligation?  I don't want to commit a sin in my ignorance.

Changing one's clothes during I'tikaaf

Q: I understand that one is allowed to change his clothes during Itikaf. In the Haram Shareef at Makkah and Madinah since there is no privacy, is it ok if one changes his clothes in the toilet when one goes to attend nature's call? Of course care is taken that one does not leave the Haram only for changing the clothes but does it when it is unavoidable to leave to fulfil the need to go to the toilet to relieve oneself.

Divorce via email

Q: My son and his wife lived together abroad. She got a baby but unfortunately died before birth. On the advice of a doctor, she came back to Pakistan for her treatment. After sometime, my son sent an email through his computer, and wrote the divorce to his wife's email address. Divorce without any witnesses and signature. Both would like to reconcile and patch up now. I would like to know according to Islamic Shari'ah that has talaq has taken place through email or not?
