Salaah

Q: After the Fardh Salah the Imam makes Du'a in which many if not the majority of people participate, arguably making it an Ijtimai Du'a. Thereafter, the Imam stands up and gives naseehat to the assembled congregation, thereby delaying the Sunnah prayer. From the end of Salah to the end of the naseehat is between 4-5min. It may be contended that nobody is obligated to sit for the naseehat. However when the majority, if not all the people sit for the nassehat, it makes it
awkward for one or a few individuals to depart to perform their Sunnah as:

(a) People are in the way and get inconvenienced.

(b) Persons draw uncomfortable attention to themselves by getting up and leaving.

Is delaying the Sunnah for this duration or at all permissible?

If not, what is the proof that such a delay is impermissible?

Q:

1. Zaid is performing Salaah alone. He calls out the Iqaamah for his Fardh Salaah, but then realizes that he has not yet performed his Sunnat-e-Muakkadah Salaah. What should Zaid do in such an instance?
2. Would the ruling change if a Sunnat-e-Ghair-Muakkadah Salaah was not yet performed before he had given the Iqaamah?

Q: Praying with paper money in ones wallet. Should we assume the paper to be clean as people could have touched them with najis hands while using it, like eating pork then touching it. I live in Holland and dutch people who are not Muslims eat pork.

Q: If you are wearing a perfume that has alcohol in it, can you pray salaah with that clothes?

Q: What is the reason that if in the first or second rakaat Surah Fatiha is repeated twice (or half of more) it does require Sajdah Sahw, but if it is repeated in the 3rd or 4th rakaat, it does not require Sajdah Sahw?

Q: If one repeats Surah Fatiha in the 3rd or 4th rakaat of a fardh Salaah, will sajdah sahw be waajib? 

Q: Is it permissible to look quickly at the clock whilst reading sunnats, to make sure one does not read too long rakaats and miss the takbir oola?

Q: If there are multiple azaans being heard at the same time, should one reply only to one or to all that one can hear clearly?

Q: Will sajdah sahw be performed when missing out a wajib in sunnah and nafl prayers also?

Q: I work in a hospital, Peterborough, UK as a medical consultant physician which 58 miles away from my house, Nottingham. I stay in hospital accommodation for 5 nights and I return to Nottingham for 2 night. Whilst in Peterborough I do attend the salah in jamaat in the local masjid, Peterborough for Fajr, Asr, Magrib and Isha.

1. With regards to sunaah and wajib do I have to do full as a mukim?

Besides, during zohr prayer I cannot go to the masjid but I do salah al Qasr if other people are not around in the hospital prayer room. I recently come across a hadith in Arba'een of Imam Nawawi RA that if a person is punctual with four sunnats of zuhr and two thereafter, Allaah will make hell forbidden for him. I just feel that I am missing this great blessing if I do salah al Qasr during zohr time.

2. In light the above, can I perform four sunnats of zuhr and two thereafter, in order to derive the above benefit? Mufti Sahib I would appreciate if you could give a comprehensive fatwaa.
