A:
Entertaining oneself can be done by not overburdening the self with loads of work or difficult actions or having to continue to do the same routine and indulge in hardship and this should be done without violating what Allah (Exalted be He) has ordained and without doing what has been forbidden. Allah (Exalted be He) does not burden anyone beyond his capacity. He (Exalted be He) did not legislate for His servants anything that might trouble them. Allah (Glorified be He) says,
Allâh burdens not a person beyond his scope.
And:
...and He has not laid upon you in religion any hardship
and:
So keep your duty to Allâh and fear Him as much as you can
It was authentically reported that the Prophet (peace be upon him) said,
Do as many deeds that are within your ability
and:
When I command you to do anything, do of it as much as you possibly can, and when I forbid you to do anything, then abandon it.
