“Abu ‘Abd Allah (a.s.), was asked about the limit of the miles which is involved in Taqsir (reducing Salah (prayer) on a journey after traveling a certain distance). Abu ‘Abd Allah (a.s.), said, ‘The Messenger of Allah had determined the limits of such mile to be from the shadow of ‘Ayr to the shadow of O’ Ayr and they are two mountains in al-Madinah. On sunrise the shadow of ‘Ayr falls on the shadow of O’ Ayr and that is the mile that the Messenger of Allah had set up for Taqsir (reducing Salah (prayer) on a journey after traveling a certain distance).”’
