Salaah

Q: If in salah on my own, I am reciting out loud and I recite bismillah out loud, and half way through it I stop, and re-recite it silently, is my salah invalidated? Also, is it invalidated if I recite it out loud and complete the recitation of it out loud only to re-recite it silently? I also have the same question but instead of Bismillah, I recite ameen out loud. Does reciting ameen out loud invalidate the prayer? also, if it does, would rectifying the ameen out loud by reciting it again straight after silently, cause the prayer to be valid again? Another question I have is that during the salah, I said some of the takbeers out loud and others including possibly 'Sami Allahu liman hamida' silently. Would this inconsistency render my salah invalid?

Q: If you are in doubt or feel that you have mispronounced parts of the quran during salah unintentionally, should you readdress this during the salah and re-recite the ayah you felt you may have made a mistake in, or should you carry on reciting?

Q: I was wondering if sajda sahw is necessary when one enters into jalsa and before putting his hands on his thighs, begins saying 'allahuma aghfirlee wa arhamnee', putting them on his hands during the recitation of the dua. Also, if the back is not completely straight during rukoo, then is the salah invalidated?

Q: Is there any dua that we need to recite between the two sujood of a rakaat in salaah?

Q: Regarding tasbeeh e fathimi after salaah, and the view of the ulama that it's better to read it after performing Sunnats, does this mean tasbeeh e fathimi should be read after nawaafil, witr etc, or after the sunnat e muakkadah and before the nawaafil?

Q: Being Associated with Tablighi Jamaat, can I practise Raf-e-yadain in Salaah?

Q: Is it right that we should recite At-tahiyat and durood after the second rakaat of sunnat ghair muaqqadah?

Q: How should na-baaligh children be arranged in the suffs of the Masjid during Salaah?

Q: My mother does not want me to go to the Masjid for Maghrib and Esha Salaah. Though we only live 15-20 minutes from the nearest Masjid, our house is in a somewhat isolated area. So my mother fears me being hijacked or something similar. Hijackings etc. are common at these times and in our area, so the fear of my mother is valid. However, I do not feel it is so dire. But I could be wrong. Though I also want to perform all my Salaah in the Masjid Insha-Allah. Please advise if I have to follow this command of my mother and thus perform Maghrib and Isha Salaah at home?

Q: What is the difference in the way of offering of Sunnat-e-Muaqqadah and Sunnat Ghair Muaqqadah Salaah?
