Narrated Sahl:
I heard the Prophet saying, “A (small) place equal to an area occupied by a whip in Paradise is betterĀ than the (whole) world and whatever is in it; and an undertaking (journey) in the forenoon or inĀ the afternoon for Allah’s Cause, is better than the whole world and whatever is in it.”
Sahih Bukhari, Volume 8, Book76, Number 424
