Saying an ambiguous word of talaaq while arguing

Q: I understand that there has to be a niyyah when one says a phrase of kinaya talaaq. I wondered that if one is arguing, and one gets a feeling like wanting to divorce or a feeling like "come on do it now (leave her) and then says a kinaya statement like "go to your father", all happening in seconds, is that a clear intention that is necessarry? But if the person asks himself a few moments later did you want to definetly divorce her now by that, the answer is no. What do i do now as i dont know whether it was an intention that counted or not? 

Reciting Surah Zumar and Surah Bani Israeel before sleeping

Q: ﻗَﺎﻟَﺖْ ﻋَﺎﺋِﺸَﺔُ ﺭﺿﻰ ﺍﻟﻠﻪ ﻋﻨﻬﺎ ﻛَﺎﻥَ ﺍﻟﻨَّﺒِﻰُّ - ﺻﻠﻰ ﺍﻟﻠﻪ ﻋﻠﻴﻪ ﻭﺳﻠﻢ - ﻻَ ﻳَﻨَﺎﻡُ ﺣَﺘَّﻰ ﻳَﻘْﺮَﺃَ ﺍﻟﺰُّﻣَﺮَ ﻭَﺑَﻨِﻰ ﺇِﺳْﺮَﺍﺋِﻴﻞَ

Aisha (radhiyallahu anha) said, “Nabi (sallallahu alaihi wasallam) wouldn’t go to sleep until he read Az-Zumar and Bani Isra’il. (Collected by At-Tirmithi (3405), Ibn Khuzaymah (1/126/2) Al-Hakim (2/434) Ahmed (2/68 /122) At-Tirmithi graded this hadeeth as being Hasan Ghareeb. And Shaykh Al-Albani said “The men in the isnad are trustworthy [ Silsilahtus Saheehah 641 ]

Remembering to make sajdah sahw while reciting Durood-e-Ebrahim

Q: When sajda-e-sahw is to be done, the procedure is that it will be performed in the last qa'dah, i.e. after tashahhud, one salam to right and then 2 sujood. Sometimes due to carelessness I recite part of durood after tashahhud and then realize that I have to do sajda-e-sahw then what should I do at that moment? Should I proceed to sajda-e-sahw at that moment?

Will a foster child inherit from foster parents?

Q: When I was born my mother was mistakenly given a Muslim baby boy (someone's else's child). She fed him once, then fed him again. She realized that she doesn't "like" this baby and called for the nurses. I was born pre mature so I was in the incubator. My father took down their address as he becomes my foster brother and I cannot marry him. We have no contact with him, have never met or seen him. We would like to know if he will now inherit? (since my mother has fed him two full feeds unintentionally) If he does inherit does he inherit from my mother and father?

Sufficing on the three fardh of ghusal

Q: (I don't know whether I am a hanfi, shafi etc, so please answer accordingly)

The ghusl/ritual bath that we perform to become paak after menses, etc. have three farz/compulsory acts: washing mouth, cleaning nose, and pouring water all over the body. So if we perform ONLY and only these three acts and NOT perform the remaining acts like performing "Wuzu", washing wrists (not the one in wuzu), doing niyyat, etc. will our ghusl be valid and will we become paak?

Also, if I only perform these three acts and that too not in proper order (for example I wash my mouth and nose in the end or any other order), will my ghusl be valid and will my namaz be accepted?
