Salaah

Q: Can I pray the five Salah at home as I am a student and don't have enough time to go to Masjid and pray with the Jamat. Kindly guide me with this...

Q: If I completed my salah and forgot to do sajda sahw, how to do it after salah? After salam if I sit and recite attahiyaat and say salam on the right side and do two sajdah and say salam to both sides. Is it the correct way? 

Q: My question is that, if a person deliberately left many prayers (namaz) then how can he complete them?

Q: If I am offering prayers alone then can I read qirat (reciting Holy Quran) in a loud voice? If there is no person except me.

Q:

1. What is the status of reciting consecutive Surahs in fardh salaat? For example, reciting Surah Ikhlaas in the first rakaat and Surah Falaq in the second rakaat?

2. In fardh salaah, it makrooh to intentionally recite Surah Ikhlaas in the first rakaat and Surah Naas in the second rakaat?

3. In Witr salaah, what is the status of reciting Surah Ikhlaas in the first rakaat, Surah Falaq in the second rakaat, and Surah Naas in the third rakaat?

4. What are the two shortest Surahs that can be read in the first and second rakaat of fardh salaah?

Q: A man joined the Salaah after the Imaam completed the Surah Faatihah. Should he recite sana? 

Q: If a muqtadi performs sajda-e-sahw without turning his head to the right and saying salaam, will the salaah be valid or should he repeat it?

Q: If the Imam recites Qirat by mouth and there is only 3 lines (saffs) of musallees and the sound by mouth reaches till the 20th line (saff), but still he recites qirat using the microphone and the sound of the loud speaker reaches 5 decibles which can be heard in the building beyond the mosque. The sound level for the 1st line (saff) of musallees is about 95 decibles (dB).

1. Though the mouth is enough, still using the mike and loud speaker, is it tasarruf?

2. When the sound level (dB) goes up beyond the permissible limit (60 dB) what should we do?

3. During the Fajr prayer when the qirat is going on so loudly, it is very difficult to pray sunnat of Fajr.
