Jamaat Salaah and Imaamat

Q: If one is travelling in a plane and wants to read salah with another brother in jamaat, in the limited space at the back of the plane would it be permissible due to space being limited:

1. The imam stands directly in front of a single muqtadi?
2. The imam stands almost next to muqtadi, just a few centimetres in front (due to space restrictions the ideal of one foot behind the imam cannot work)?
3. The imam stands on the right of the muqtadi, muqtadi behind imam one foot length?

Q: Can Hanafis in countries whose asr Salaah time is in accordance with the other three Mazhabs perform the Asr Salaah with the Jamaah without
re-performing it later when the Hanafi asr time is due?

Q: If a person led salaah intentionally without wudhu many years ago and now cannot tell each musalli because he does not know who they are
individually. How does one make up for this shameless act. The Fear of allah has entered him and it does not give him peace of mind until he knows that he is forgiven and he does not have to worry.

Q: Qiyaam-ul-layl: I am a Hanafi  living in an area where, unfortunately, many do not follow a set mazhab. One of the brothers requested that 'Qiyaam-ul-layl' be performed in jamaat during Ramadaan. From his description, I understand this to be tahajjud salaah (as we have already
arranged for Taraweeh salaah). Is it permissible to perform any nafl salaah in jamaat?

Q: Can I offer salaah with my husband and do I have to recite iqamah to offer Salah only with him?

Q: I was travelling through a certain town two Fridays ago and the Aalim that performed the Jummah Bayaan, Khutbah and Namaaz clearly had a shortened and trimmed beard. I enquired from the local people who informed me that he is an Aalim. They also informed me that the trustees and imaam are all aware of this and have done nothing about it. I was a traveller and wanted to find out what will be the status of my Salaah?

Q: Can we offer namaz behind a person who commits shirk or has the aqeedha of shirk?

Q: If the ahle hadith wash their feet with water during wuzu after taking their socks off can we offer salah behind them?

Q: Is it permissible for an Aalim who is appointed as Imam in a musjid to receive salary for Imamat whereas the five times salaah is obligatory for
the imam also and also it is a duty of a muslim who keeps the knowledge of fiqh and recites quran properly to lead the salah only for the sake of Allah without a salary?

Q: When the Imam says Sami Allah Huli man Hamidah, I try to say Rabbana Wa la kalhamd. But before I finish saying it, the imam says Allah Hu Akbar and goes into sajdah before I have finished saying Rabbana Wa la kalhamd. In this case, should I:

1. Stop saying  Rabbana Wa la kal hamd as soon as the Imaam says the takbir and goes into sajdah?
2. Continue to say Rabbana Wa la kalhamd while following the imam into sajdah?
3. Do not say Rabbana Wa la kalhamd at all knowing that I won't finish it in time before the imam goes into sajdah.
