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.

Q: I have seen scores of pigeons roosting in many Masjids.  They keep flying around and a lot of their droppings are found on the prayer mat, some dry and some fresh.  I had the opportunity to witness so much droppings continuously being made by the pigeons roosting in Jama Masjid in Delhi during my visit once, when I had gone to offer my Dhuhr Salaah with the Jamaath.

I require the following clarification.

1. Is our Salaah valid if offered at such a place full of pigeons' droppings, dry or fresh?

2. Do we have to clean only the spot of the droppings if they fall on our clothes if we are in a state of Wudhu or do we have to do our Wudhu all over
again?

3. Similarly, I have witnessed the same scenes at many Eidgahs in different cities during my travel, during Eid Salaah, where sheep/goat droppings/cattle dung are found all around dry or fresh, which the people responsible for the maintenance of the Eidgahs neglect to clean. Is our Salaah valid in such places?  

4. What is the Shariah Ruling on these kind of najis?
