Times of Salaah

Mustahab times for salaah

Q:

1. If the asr time starts at 3.57 and sun sets is at 5.32, what is the mustahab time to perform asr and when does the makrooh time start?

2. If fajr starts at 5.25 and magrib starts at 5.34 what is the mustahab time to pray esha?

3. My salah app shows that sehri or tahajjud time ends at 5.16 and fajr starts at 5.25, Can I pray tahajjud between this time? 

Joining salaahs

Q: If one has oral surgery due to having a wisdom tooth removed, and therefore has constant bleeding in their mouth for days, are they allowed to join prayers? If so how long are they allowed to join prayers? Is it until the pain ends or until the bleeding stops?

Salaah time expiring while one is performing Salaah

Q: If salah was delayed nearing to the end of its time and the takbeer for commencing the salah was made within the time, for example within dhuhr time, however, the salah was completed when asr time set in then will the salah be counted as a qadha salah or will it officially count and also will this count as missing salah within its time thus meaning one is sinful or will it be sinful for other reasons such as the sin for delaying and is there a difference in severity between these two sins?

Hanafi performing asr salaah in Shaafi'ee time

Q: When we go for umrah, all the umrah busses stop for asr prayer according to shafiee time. We (ladies) strictly follow hanafi time. In winters, due to school, we read our zuhur salah after the shafiee asr azan, as hanafi zuhur salaah time is still there. We also read our asr according to hanafi time i.e. late.

So my question is... the bus stops for asr at shafiee time. If we do not get the jamaat, what should we do? Can we read at shafiee time at such circumstances?
