What is the travel limit to offer Qasr? Also, if I am leaving back from home from the destination which falls in Qasr Category and its already time to offer Isha but I drive back home and then want to offer Salat-e-Isha so in this case will I offer full prayer or Qasr for Isha?
If one travels away from with the intention of 48 miles or more, then this person will be considered a Musafir and will be required to perform Qasr Salah i.e. 4 Rak'ah Salah will become 2.
A person may continue to perform Qasr Salah as long as the journey continues or the stay at temporary destination is less than 15 day. Once a person return home and enter his home town, he must abandon the Qasr Salah and offer complete Salah.
If one was a traveler when the time for Isha, Zuhr or Asr started but he chose not to offer Salah then, instead he came home and offered Salah, then he must offer complete Salah.
The concession of Qasr is lifted upon entering one's hometown.
And Allah knows best.
