Talaaq-e-baain

Q: My husband and I fight a lot where he threatens to send me back to my parents home. Recently while fighting he said he doesn't want me anymore and he's tired of me. So after much arguing, I asked him if we married, yes or no. His answer was no. Does this go as a talaaq?

Qailoolah

Q: What is the correct time for qailoolah? If a person rests even before zawal e.g. 11 am, would this also be considered qailoolah?

Omitting a Surah in-between two Surahs

Q: I have been told that if, for example one reads surah Nasr in the first rakaat, then in the next rakaat one cannot read surah Ikhlaas. One must recite the surah immediately thereafter or there should be at least a gap of two surahs. Please clarify this rule for me (e.g., does it apply only to short surahs? Does it apply to a 4 rakaat salaah as well?)

Reciting a portion of one surah in the first rakaat and reciting a portion of another Surah in the second rakaat

Q: If a person recites from the middle of one surah in one rakaat and from the middle of another surah in the second rakaat or if a person recites from the end of one surah in one rakaat and from the end of another surah in the second rakaat of a fardh Salaah, will the Salaah be valid?
