Shaykh Muhammad bin Saalih al-‘Uthaymeen رحمه الله, stated:
“A
person’s lifespan in reality is that which he spent in
obedience to Allaah,
The Mighty and Majestic. As for that which he did not spend in obedience of
Allaah then it is indeed a loss,
and it will either be against him (it will earn him sins), or it will neither be for him nor against him (no
sin and no reward).”
