Method of Salaah

Q: In a 4 rakaat Sunnah salaah, if in the first 2 rakaat one reads e.g. 1 page in each rakaat. Is it fine in the 3rd and 4th rakaat to read 1.5 pages? I.e more than the first two.

Q: Whilst performing a Qada prayer, one had just finished reciting "As-Salamu-Alaykum" of the first Salaam, and before one could complete "Wa Rahmatullah" (and even before the second Salaam), one's wudhu broke. Is this prayer to be repeated?

Q: Can dua be made in Sujood after having prayed the fardh Salaah?

Q: After ruku I used to say sami Allah huliman hamida (without ha in the end) and no Ayn at Allah, will this make my salah invalid?

Q: I want to know what are the faraaidh of Salaah?

Q: In ruku should the arms be kept straight or should they be bent with the elbows sticking out?

Q: What I wanted to ask you is that how can one make dua in sujood? Is it allowed for one to make dua in a speaking way in sujood or you just make dua in your heart when in sujood and the second thing is that I want to know how to make dua to Allah Ta'ala and at what time when some one has wronged you, has hurt you etc, what should I pray to just complain about that person to Allah Ta'ala?

Q:

1. Should one's heels be apart or touching whilst in sujood? Is this sunnah? If so which part of the foot should be touching each other as a lot of people are not aware of this?

2. If one recites bismillah in the 3rd or 4th rakaat of a fadh salaah after surah fatiha as though he is going to recite a surah, but then realises and doesn't proceed with the surah, would this require sajda-e-sahw?

Q: Our local Imaam recites long Surahs in Maghrib Salaah and very short Surahs in Esha Salaah. My understanding is that it should be other way around. Please advise the correct procedure especially in the light of the sunnah of Rasulullah (Sallallahu Alayhi Wasallam).

Q: Before going to the Masjid for salaah or when performing Nafl Salaah at home, I aply Itr, comb my hair, apply some olive oil to my beard, use the Miswaak, and ensure that my kurta is clean. What intention should I make before doing these actions?
