Salaah

Q: How many sunnats are there in the night before bed? Please explain in detail.

Q: Please explain the salaah posture for a female. Do the arms remain close to the body and flat on the floor or raised? Please explain the complete postures from beginning to end. May Allah reward you most kind.

Q: I read a book called Umdat ul Islam written by Abdulaziz bin Hamidullah in Persian some 700 years ago that if one reads the word hamida of sami Allahu liman hamidah with the letter ه instead of ح the salaah becomes faasid. Is this correct, it was also written that if you read Allahumma salli, the word salli with a س and not a ص the salaah is faasid. 

The book in question is it a authorative book? It says also some strange things like that in Jami al Fatawa it is said that if a person makes zina with a animal the animal should be killed and burned, and the person should also burned or a wall should thrown on him.

Q: Should I perform my namaz on the train if it is namaaz time?

Q: When I make sajdah, I am not satisfied and I push my head too hard. I want to know the correct way of making sajda. How much pressure is requried? Where exactly should the floor touch the nose and forehead? Anywhere or some precise position is required?

Q: In my namaz whenever something comes in my mind, even if I try to regain my concentration I forget what I read, in which rakaat I am and many other similar things. What should I do? 

Q: When I was young and ignorant, I used to have bad habits. Two of these included masturbation as well as neglect of salaah. Nevertheless, Alhamdulillah, with the Hidayat of Allah I have mended my ways. My question is, I want to make up for the missed Salaah. Should I start making up from when I was 15, or from when I was 12 when I ejaculated? I am not sure when my ejaculations were clear and when it started becoming milky in appearance.

Q: Do I need to perform Sunnat-e-muakkadah of each Salaah for Qadha-e-umri?

Q: I am 18 and currently studying in university. During Ramadhaan, I used to pray 5 times a day and would read Qur'an everyday. But ever since Ramadhaan ended, I haven't been praying my Salaah very often. I really want to start praying 5 times a day but I don't know how to start. Every time I think of starting to pray, I become lazy and delay my Salaah. Please tell me what I should do to start praying everyday and come closer to my Deen. I've wasted a lot of time doing useless things rather then praying my Salaah. If I start praying 5 times a day, will Allah Ta'ala forgive me for not praying my past Salaahs?

Q: Must one make sajda-e-sahw if one misses the ruku in the last raka'ah in witr?
