Ruling 1258

If a person’s outward and return journey totals eight farsakhs – irrespective of whether or not the outward or the return journey on its own is less than four farsakhs – he must perform qaṣr prayers. Therefore, if his outward journey is three farsakhs and his return is five, or vice versa, he must perform qaṣr prayers, i.e. [he must perform the four rakʿah prayers] as two rakʿah prayers.
