The Hanafi and Shaafi?ee times reflected on Salaat timetables are generally for the commencing time of Asr Salaat.
According to Imaam Abu Hanifa, the terminating time for Dhuhr Salaat is when the shadow of any object reaches twice its length excluding the shadow during midday. That is when Asr Salaat sets in. According to the majority Imaams, that includes Imaam Shaafi?ee (RA), the terminating time for Dhuhr Salaat is when the shadow of any object reaches one length excluding the shadow at midday. That is when the time for Asr Salaat sets in. According to Imaam Abu Hanifa (RA), that is still time for Dhuhr Salaat.
The different times on the timetable assists one to perform Salaat timeously according to his Madhab.
