Method of Salaah

Q: One who reads only the word ha meem or yaseen in salaah, will it suffice for the fardh of qiraat?

Q: If we perform a fardh salaah which have sunnah muakkadah after it (zuhr, magrib, isha), when should we read dua after salaah? After the fardh salaah or after the sunnah muakkadah salaah, or after both?

Q: How long is it waajib for jalsah in salaah?

Q: In s​alaah after ruku while standing when one is reading rabana walakal hamd. Is salaah valid if most of rabana walakal hamd was read standing and maybe a little while moving down? If not and one just bent his knees a bit and moved his hands forward, then is it valid? 

Q: If one has to recite only one Ayah in a rakat of a Salah how long it should be?

Q: It is mentioned that a person's dua will be answered if he makes duaa after the fardh salaah. Does this mean that he should make dua after the fardh of the salaah or after the entire salaah is completed?

Q: In the last rakaat, in tashahhud, after at tahiyyaat, my wudhu broke, is my namaaz done?

Q: I was raised in a Hanafi family and I pray my salat according to the Hanafi school. But recently I found out that prophets prayer was a little bit different than the way Hanafis pray. For example, Hanafis DONT raise their hands before going to the Rukuh and while straightening up from the Rukuh. So I was thinking should I start praying like the way Hanbalis pray? I go to a Hanafi masjid. Can I pray like this over or should I act like a pure Hanafi?

Q: What are the dua's whilst in sajdah?

Q: A person does forget one the fard acts of salaah and remembers this after the time for that prayer expired. A fatwa was writing that is mustahab to repeat the prayer. Pleasr give your input.
