Narrated Sahl bin Sad Al-Saidi (Radi-Allahu 'anhu):

Allah's Apostle (Sallallahu 'Alaihi Wa Sallam) said, "A place in Paradise
equal to the size of a lash is better than the whole world and whatever is
in it."

This gives us the lesson that we should try hard and hard to earn more space in Paradise because that will be the Real Wealth at the end !!!
