The Noble Messenger of Allah, Sallallahu alaihi Wasallam, said:
"THE LIFE OF THIS WORLD COMPARED TO THE HEREAFTER IS AS
IF ONE OF YOU WERE TO PUT HIS FINGER IN THE OCEAN AND TAKE
IT OUT AGAIN; THEN COMPARE THE WATER THAT REMAINS ON HIS
FINGER TO THE WATER THAT REMAINS IN THE OCEAN." [Muslim].
Need we say more? It is incumbent that we work hard for life in the Herafter, while relying on Allah's Mercy and Forgiveness.
