The World Federation One Stop Fiqh

Ruling 756

The nāfilah of ʿaṣr is performed before the ʿaṣr prayer, and its time continues until the time it is possible to perform it before performing the ʿaṣr prayer. However, if one delays performing the nāfilah of ʿaṣr until the time that the shadow of an indicator becomes four-sevenths the length of the indicator, it is better to perform the ʿaṣr prayer before the nāfilah prayer, except in the case mentioned in the previous ruling.
