Ruling 1268

A traveller must perform qaṣr prayers when he has decided to travel eight farsakhs. Therefore, if someone goes out of his town and, for example, his intention is that if he finds a friend he will travel for eight farsakhs, then in the event that he is confident that he will find a friend, he must perform qaṣr prayers; and if he is not confident about this, he must perform tamām prayers.
