Salaah

Q: In the third and/or fourth rakaat of a faraz namaaz, or in the third raakat of Magreb, after surah Faatiah, one inadvertently recites tasmiyah and is about to recite a surah but realises one’s error and goes into ruku.  Is Sajdah - e - Sahw necessary?

Q: If I perform a fard salaat on my own and someone joins in,what is the procedure? My intention was not as an Imam. I am reading silently, do I continue aloud?

Q: Zeid doesn't pray salaat regularly because of laziness. He has been told by a Hanafi maulana that this is not kufr (however it is fisq). But, there is an opinion related from Imam Ahmad that leaving salat because of laziness is kufr. If Imam Ahmad's opinion turns out to be the correct one, what will happen to Zeid? Will he be a kafir who is forever destined for hell, or will he be excused since he is a Hanafi and acted according to the information given to him by Hanafi ulema?

Q: For Fardh and Wajib Salaahs:

1. Is it necessary to state the number of rakaats you are praying? i.e I am praying 3 rakaats maghrib, 2 rakaat fajr etc
2. Is it sufficient to just state the salaah i.e I am praying Fajr ,Maghrib etc?

Q: I have heard that it is mentioned in the hadith that a lady who reads her salaah at awwal waqt gets the reward of reading salah with jamaat Takbir e oola etc. Is this correct. What about if a lady reads her salaah at the same time as the men in the musjid does she still get this reward? Should one set the salaah times for the ladies in the home in order to get this sawaab?

Q:

1. Someone prays all Salaahs on time except the Fajr prayer which he misses for many reasons. One is that he watches TV, etc. Will Allah (SWT) accept from him the four prayers if he doesn't pray Salat Al-Fajr? 
2. I have sleep problem, I don't fall asleep easily.  I try using alarm to wake me up for fajr salah but it doesn't works.  If I wake up for fajr I can't fall asleep again so can I pray fajr as qaza during zuhr time, praying as qaza would fajr be valid?

Q: My question is about "taqlid after amaal".

If a Hanafi after salaah, finds out his salaah was not valid according to the Hanafi madhab, but it is valid according to for example Hanbali madhab, can he follow that madhab and suffice with salaah he has prayed?

Q: In the Hanafi madhab, if you remain silent (during prayer) for a time period where one can recite "Subhan Allah" 3 times, then it becomes waajib for the person to perform Sajdah Sahw. If, however, the individual did not perform Sajdah Sahw, does he then have to repeat his prayer? What if, in the past, the person did not pay attention to this fact during his prayer, and he now has several prayers where he was required to perform Sajdah Sahw, but he did not do so. Does he have to repeat all those prayers?

Q: When the Azaan is going on, can one continue reading the Quran, is this considered sinful?

Q: After fajr and asar Salah, the Imaam saheb sits facing the muqtadi. Why?
