(When ye have performed the act of worship) when you have finished performing the prayer of fear, (remember Allah) pray to Allah, (standing) for the one who is healthy, (sitting) for the one who is sick (and reclining) for the one who is wounded or sick. (And when ye are in safety) when you return home and feel no more fear, (observe proper worship) perform the prayer in full: four units of prayer. (Worship at fixed hours hath been) performing the prayer is (enjoined on the believers) prescribed and known both while in residence and during travel: the traveller performs two units of prayer and the resident four.
