Indeed, the one who said the following was right:
If you are alone for a time one day, don’t say:
“I am alone.”
“There is a Watchful Guardian over me.”
And don’t think that Allāh is ever heedless
Or that what is hidden from Him is unseen.
Do you not see that the days pass quickly
And that tomorrow is close for those who are heedful?
