An-Nisaa 4:103

When you have finished the prayer, remember Allah, standing, sitting, or lying down. But when you are safe again, establish regular prayer. Indeed, prayer is prescribed for the believers at specific times.

And when you have completed the prayer, remember Allāh standing, sitting, or [lying] on your sides. But when you become secure, re-establish [regular] prayer. Indeed, prayer has been decreed upon the believers a decree of specified times.

103. When you have finished As-Salât (the congregational prayer), remember Allâh standing, sitting down, and (lying down) on your sides, but when you are free from danger, perform As-Salât (Iqamat-as-Salât). Verily, As-Salât (the prayer) is enjoined on the believers at fixed hours.

When ye have performed the act of worship, remember Allah, standing, sitting and reclining. And when ye are in safety, observe proper worship. Worship at fixed times hath been enjoined on the believers.
