The name "Hanfa"

Q: We are expeting a baby in few days. I am a bit confused about the name. I searched in many muslims websites it shows the meaning of (HANFA) wife of prophet Ismail (Alayhis Salaam). I want to make sure the name HANFA is correct before calling my new baby. 

Women's voice

Q: Is a woman's voice part of her ourah? I learned that the wakeel of a woman must first give way to her before she can be allowed to speak to a man other than a direct male relative of her family. I ask because I hear woman speak freely on the Islamic radio stations and it doesn't sound right.

Thanking someone

Q: When someone does good to you, is it Sunnah to say:

  1. Jazakallah
  2. Jazak Allah Khair
  3. Or Jazak Allah Khayran?

What was the practise of Prophet Sallallahu alaihi wasallam and the Sahaba R.A, please provide reference?

Dream

Q: One person proposed for me and I did estikhara for him. I saw a dream on the first night that a room is full of girls who are pregenant and some of them were known to me and the room was maybe be a clinic. I can't undertand the dream but when I woke up, I felt no burden on my heart and I was peacefull.
