Reciting Sami Allahu liman Hamidah instead of Subhana Rabiyal A'laa

Q: When performing Salaah behind the Imaam, in the sujud after saying a few times "subhana rabbiyal alaa" somehow I was about to say "sami Allahu liman hamidah" but as soon as i said "sami Al" I realisized and cutt off and continued saying "subhana rabbiyal alaa". Now was my prayed invalidated since I cutt of at the half? Must I repeat it?

Taking one's naffs as one's ilaah

Q: My question is about an ayat in a quran that says, "those who take there nuffs as there illah". What does this ayat mean? 

Can it be possible that  a person goes to his wife, and be worshipping his nuffs even though he goes to his wife and has intercourse in a  way allowed in shariah. What if he is behaving like an animal or acts upon his animal qualities. Is this allowed in sharia? I am not married yet but I am afraid to get married because of tasswuf and wazifahs and the effects they have upon me.
