Robert Louis Stevenson said;
"Every person is capable of performing his daily tasks, no matter how difficult they are, and every person is capable of living happily during his day until the sun sets: and this is the meaning of life."
Stephen Leacock said:
"The young child says: when I will become a bigger boy. The boy says: when I become a teenager, and when that time comes, he says: when I will many. What about after marriage? And what comes after all of these stages? One’s thoughts constantly follow the tune of the following: when I will be able to retire. But when one actually reaches old age and looks back, he is scorched by a cold wind. He lost out on his whole life that dwindled away without ever living inside of it. And thus we learn, only when it is too late, that life is to be lived in every breathing minute and hour.”
Such is the state of those who put off repenting from their sins.
One of our pious predecessors said:
"I warn you of delaying and saying that I will do it later, for this is a phrase that prevents one from doing good and causes one to fall behind in deeds of righteousness?
(Leave them to eat and enjoy and let them be preoccupied with (false) hope. They will come to know!) (Qur’an 15: 3)
The French philosopher, Montaigne, said:
"My life was filled with bad luck that never showed mercy."
I assert that despite their knowledge and intelligence, many famous thinkers knew nothing of the wisdom behind their own creation. They were not guided by the teachings that Allah sent through His Messenger, Muhammad (bpuh).
(And he for whom Allah has not appointed light, for him there is no light.)
(Qur’an 24: 40)
(Verily, We showed him the way, whether he be grateful or ungrateful.)
(Qur’an 76: 3)
"Consider that this day will not occur again."
Better and more beautiful and complete is the hadith:
"Pray as if it is your farewell prayer."
Whoever puts it into his mind that today is his last day, will make a fresh repentance, will do good deeds, and will strive to be obedient to his Lord, the Almighty and His Messenger (bpuh).
