Times of Salaah

End of Zuhr time

Q: What time does Zohar Salaah become Qadha. Does Zohar end at the time Asr starts? I see that the Shafi time for Asr is 15:15 and for Hanafi it is 16:03. I do understand the the shadow of an object needs to be twice the original size plus the bit that was there at midday. I am asking in regards to the times for the Salaah. This is the time in Durban.

Beginning of Asr time according to Hanafi Mazhab

Q:

1. There are two times for the starting of Asr Salah. The earlier time is according to the Sha'afi madhab, and a later time is according to Hanafi madhab. I recently came to know that even for us as Hanafis, it is wajib to perform Zuhr salah before the start of Sha'afi Asr time, to be on the safe side and avoid the risk of our Zuhr Salah being Qaza. Is this correct?

2. If a Hanafi performs Asr Salah when the time has started according to Sha'afi madhab but according to Hanafi madhab the time has still not entered, is his Salah valid? Does he have to repeat the Salah? (This is a very common problem in many Western countries where Hanafis print out Salah timetables from the Internet and the Asr time displayed there is according to Sha'afi madhab. So these people then perform Asr salah before the Hanafi time).

3. In some non-Hanafi countries, Asr Salah is performed in the Masajid before the Hanafi time. In this case, a Hanafi person has two choices, either to perform Salah with Jamaat before the Hanafi time or to offer it alone later on. What should he do?

4. There is a time before starting of Zuhr salah when it is prohibited to do Sajda or perform any Salah. I was under the impression that this time lasts for only ten or fifteen minutes before Zuhr. However, I came across a Salah timetable where it mentions the 'Makruh' time before Zuhr. For Durban, South Africa for 3rd April, this Makruh time has a duration of 38 minutes, lasting from 11.22 a.m till 12.00 pm. Is this correct?
