Elvin said to Manu ,'' open the window.''( reported speech direct to indirect )

Elvin told Many to open the window.

Explanation:

In this case, we must report an imperative sentence. When that happens, it is best to use verbs such as "tell", "ask", or "order" instead of "say". Then, before the imperative verb, we add "to", if it is an affirmative imperative. In case it is negative, we add "not to". Take a look at the examples below:

- Sarah said to Chris, "Leave me alone!" - Sarah asked Chris to leave her alone.

- Jenny said to Lisa, "Don't go in there." - Jenny told Lisa not to go in there.

Having that in mind, we can safely change the sentence below from direct to indirect speech:

Elvin said to Manu, "open the window." --> Elvin told Manu to open the window.

imparadis't in one anothers arms  

the happier eden, shall enjoy their fill  

of bliss on bliss, while i to hell am thrust,  

where neither joy nor love, but fierce desire,  

among our other torments not the least,  

still unfulfill'd with pain of longing pines;  

yet let me not forget what i have gain'd  

from their own mouths; all is not theirs it seems:  

one fatal tree there stands of knowledge call'd,  

forbidden them to taste: knowledge forbidd'n?  

suspicious, reasonless. why should their lord  

envie them that? can it be sin to know,
