Masbooq and Laahiq

Q: If I missed the first rakha and joined in second one. During the salah imam made a mistake and at last did sajda-e-sahw. Should I complete the first rakaat or not?

Q: I had missed two rakahs of maghrib in Jama'ah, so I continued to offer them after the Imaam said salaam. But I recited a surah in both the rakahs, thinking that my prayer would otherwise have only one surah recited. Is this correct?

Q: When one misses a rakaat with Jamaat, as one stands up, do you start with Thana or Sura Faatiha.

Q: When namaz is being performed in congregation and I joined as muqtadi after third rakath and after Salam I will have to pray the due rakat, while performing my due rakath can other muqtadi join me which makes me imam to new muqtad?

Q: I am a follower of the Shaafi'i mazhab. In our musjid, which is mainly Shaafi'i the Somalian brothers will join a masbooq who has missed a few raka'ats and they will then follow the masbooq as if he is the Imaam.

1. Is this correct? If yes how should it be done.

2. What should you do if you are the masbooq and someone taps your shoulder or just joins your Salaah to follow you? Your input in this regard is greatly appreciated.

Q: If a person standing in the first saff commenced the Salaah with the Imaam. During the Salaah, his wudhu broke and therefore he left to perform wudhu and make bina of his Salaah. After returning, if he stood in the back saff, will he receive the reward of the first saff?

Q: Mufti sahab, I joined the imam in congregation salaah while the imaam was in ruku and I didn't get time to say subhana rabbiyal azeem? Did I get that rakaat? When does a person get the rakaat?

Q: In hanafi fiqh, if for e.g. in dhuhr salah I enter the salah in the 2nd rakat. i.e. I have to pray one rakah after the imam's salah is over, so in the aakhiri qa'ida with the Imam, I have to recite only Tashahhud or Tashahhud and durood shareef?

Q: Can you please explain to me the method of namaaz if I miss 1, 2 or 3 rakaats with jamaat?

Q: I joined the Asr salaah when the Imam was coming up from ruku in the second rakaat. While he was coming up from ruku I joined the Salaah and went into ruku by accident. At the end of the salaah, I stood up and completed two rakaats and made sajda-e-sahw. Is the Salaah valid?
