Who said Ah, but here's the rub?

Question

IS THIS A QUOTATION FROM SHAKESPEARE?

Answer 1

The phrase is from Shakespeare, but it is not quoted correctly in your question. The correct phrase is, "Ay, THERE'S the rub!"

It comes from Hamlet’s famous “To be or not to be” soliloquy:

To die — to sleep.
To sleep — perchance to dream: ay, there’s the rub!
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause.

Answer 2

Hamlet says -Now there's the rub,for in this sleep,what dreams may come,when we have shuffled of this mortal coil etc.The famous speech which starts-To be, or not to be-

Answer 3

The phrase "to be, or not to be" comes from Shakespeare's Hamlet, Prince of Denmark, Act III, scene I, and it is often used in reference to the whole speech the line opens. The soliloquy, spoken in the play by the eponymous character, follows in its entirety:
The bit you refer to is in line 10

“ To be or not to be, that is the question;
Whether 'tis nobler in the mind to suffer
The slings and arrows of outrageous fortune,
Or to take arms against a sea of troubles,
And by opposing, end them. To die, to sleep;
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That flesh is heir to — 'tis a consummation
Devoutly to be wish'd. To die, to sleep;
To sleep, perchance to dream. Ay, there's the rub,
For in that sleep of death what dreams may come,
When we have shuffled off this mortal coil,
Must give us pause. There's the respect
That makes calamity of so long life,
For who would bear the whips and scorns of time,
Th'oppressor's wrong, the proud man's contumely,
The pangs of despised love, the law's delay,
The insolence of office, and the spurns
That patient merit of th'unworthy takes,
When he himself might his quietus make
With a bare bodkin? who would fardels bear,
To grunt and sweat under a weary life,
But that the dread of something after death,
The undiscovered country from whose bourn
No traveller returns, puzzles the will,
And makes us rather bear those ills we have
Than fly to others that we know not of?
Thus conscience does make cowards of us all,
And thus the native hue of resolution
Is sicklied o'er with the pale cast of thought,
And enterprises of great pitch and moment
With this regard their currents turn awry,
And lose the name of action.
