Kitáb-i-Aqdas

Question: Concerning the holy verse: "When travelling, if ye should stop and rest in some safe spot, perform ye ... a single prostration in place of each unsaid Obligatory Prayer..."

Answer: This prostration is to compensate for obligatory prayer omitted in the course of travel, and by reason of insecure circumstances. If, at the time of prayer, the traveller should find himself at rest in a secure place, he should perform that prayer. This provision regarding the compensating prostration applieth both at home and on a journey.
