The Command to remember Allah during Spare Time

﴿ فَإِذَا فَرَغۡتَ فَٱنصَبۡ • وَإِلَىٰ رَبِّكَ فَٱرۡغَب ﴾

( So when you have finished, devote yourself to Allah's worship. And to your Lord turn intentions and hopes. )

Meaning, 'when you have completed your worldly affairs and its tasks, and you have broken away from its routine, then get up to perform the worship, and stand for it with zeal, complete devotion and purify your intention and desire for your lord.' Similar to this is the Prophet's statement in a hadith that is agreed-upon to be authentic,

لَا صَلَاةَ بِحَضْرَةِ الطَّعَامِ, وَلَا هُوَ يُدَافِعُهُ الأَخْبَثَانِ

There is no prayer when the food is served, nor when the two foul things (excrement and urine) are pressing a person.

The Prophet (صلى الله عليه و سلم) also said,

إِذَا أُقِيمَتِ الصَّلَاةُ وَحَضَرَ الْعَشَاءُ فَبْدَأُوا بِااْلْعَشَاءِ

When the prayer has started and the dinner has been served, then begin with dinner.

Mujahid said concerning this Ayah, "When you are free from the worldly affairs, and you have stood to pray, then stand up for your Lord."
