Ahmed Raza Khan: Mohammed Aqib Qadri:
So when you have offered your prayers remember Allah while standing, sitting and reclining; and when you feel secure, offer prayers in the usual manner; indeed prayers are a time bound obligatory duty upon the Muslims.

Yusuf Ali:
When ye pass (Congregational) prayers, celebrate Allah's praises, standing, sitting down, or lying down on your sides; but when ye are free from danger, set up Regular Prayers: For such prayers are enjoined on believers at stated times.

Pickthal:
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.
