Salaah

Q: Can one pray nafl salah after having prayed sunnah salah if time permits before the jamaat for the fardh salah starts?

Q:

1. Is reciting bismillahir rahmanir raheem before alhamdu in namaz obligatory? If one doesn't read bismillah before alhamdu, either in the first or second, third or 4th rakaat is their salah nullified?

2. Is reciting rabbigh firli in between sajadah obligitory? If one doesn't recite this inbetween sajda and just says subhana rabbiyal a'ala in sajadah and sits and says Allahu akbar and then goes into sajadah again and says subhana rabbiyal a'ala, is this incomplete and is the namaz nullified because the believer didn't say rabbigh firli between the sajadah?

3. Is it obligitory to say bismillah before or after any surah during namaz? If one doesn't, is their namaz invalid?

4. If a woman reads silently where her lips and tongue is moving but you cannot hear her, are her prayers invalid? She lives in a joint family, where her husband's cousins, both male and female come and go and she cannot say for sure who is at home and who isn't. It is a 3 floor house, with she occupying one room and the opposite room belongs to her husband's uncle and her husband's cousins.

5. If a woman has been praying normally but hasn't been saying bismillahir rahmanir raheem before surah fatiha (as in scenario 1) and hasnt been saying rabbigh firli in between the sajadah (scenario 2) and hasnt been saying bismillahir rahmanir raheem before or after any surah in namaz (as in scenario 3), and has been reading quietly and has been moving her lips and tongue and no one is able to hear her, has all her namaz been invalid if she has been praying like this? She was unaware that a woman is to pray aloud she knew reading quran should be read in a tone one can hear themself but she didnt know you are suppose to hear yourself during namaz 

Q: I always feel like I did a mistake in prayer so I always prostrate twice after I say salaam. While I was doing prayer today, in my mind something came that said if I prostrate, I prostrated to something other than Allah but I still prostrated. Did I commit shirk?

Q: Do we have to reply and read the dua after listening to azaan on the al-fajr clock?

Q: In some masjids, there is a seperate entrance, like a connecting room, before the main praying hall, where people keep their shoes. The doors of the masjid first open into this entrance, and then there is another door to the main praying hall where the imam leads the salaah. Often this area is carpetted for praying. Is it allowed to make a second congregation (jamaat) in this entrance?

Q: After I became baligh, I would offer my prayers but mostly I would miss them. I've missed my prayers and I don't know how many prayers I've missed. It's uncountable. How can I offer my missed namaz? How will I know that my missed prayers are done? Is it possible if I offer salat-ul-toba and never miss my prayers? 

Q:

1. I usually take the least number of rakaats when I totaly get confused in the number of rakaats of salaah and complete my salaah. I don't sit for tashahud in every rakaat in this case but I do sajda e sahw in the end after reciting tashahud by saying salaam to the right side and then two prostration of forgetfulness and again tashahud then durood and dua and then salaam to right and left. Is this the right way?

2. If not, what is the ruling on my previous salaah?

3. If it is wrong what is the right procedure?

Q: Zaid has a towel ihraam which is made in such a way that there are very small holes in the ihraam cloth. When wearing the ihraam, little skin is visible from the holes. Zaid prayed salaah, did his umrah and Hajj with the above mentioned ihraam on. According to Shariah is his salaah, umrah and Hajj valid? If it isn't valid, what should be done to compensate?

Q: Can a waladuz zina (illegitimate child) make imamat for taraweeh salaah in Ramadhaan?

Q: Ever since I started becoming regular in 5 times Fardh Salaat, my facial structure has changed significantly. Sometimes I get quite surprised seeing myself in the mirror. Even my mother asked about my face and if I was I eating some new health food. Please explain this.
