Salaah

Substituting the Sunnah Muakkadah with Qadhaa Salaah

Q: A person has excessive (many years) of Qadhaa Salaah. Due to weakness, would it be correct for a person to substitute the Sunnah Muakkadah
before/after each Salaah with Qadhaa Salaah? For example, at the time of Fajr, instead of performing two Rak'aats of Sunnah Muakkadah, a person makes intention and performs two Rak'aat of Fajr Qadhaa. Or at the time of Zuhr, instead of performing four Rak'aat of Sunnah Muakkadah, a person performs four Rak'aat of Zuhr Qadhaa. Would this be correct?

Hanafi leading Shaafi'ees in Salaah

Q: I am situated an area where Hanafi madhhab is minority, and I regularly lead the salaah at the local Musallah. I am a Hanafi. Please can you clarify the following, as I don't want to create any confusion in the community:

  1. Is it permissible for me to lead the Asr salaah, even though the Shafiee time is followed?
  2. For Fajr and Zohr salaah, if I have not performed my sunnats as yet, should I decline to lead the salaah?
  3. When leading taraweeh: If majority of the jamaat performs the sajdah ​tilaawat in 17th para, and not the sajdah in 23th para, do I have to do this as well, or do I do as I have been taught?
  4. Witr in Ramadaan: Can I lead the witr, as I believe the Shafiee method is different?
  5. Recently, one of the brothers, while leading salaah performed sajdah sahw, by making both salaams, then 2 sajdahs, then immediately 2 salaams to end the ​salaah. Is the salaah correct, as I have been taught differently?
  6. I notice that the Imaams in the area say something in Arabic before the salaah, which I believe is related to straightening the saffs. Is this a sunnat, and if so, what exactly should I say.
