Question

she said to abhilash don't make a noise into direct speech

Answer 1

Hello!

To your kind notice, the sentence you have stated above itself is direct speech.

To make it more clear, I can do this:

She said to Abhilash, "Don't make a noise".

Answer 2

Direct speech is the repetition of actual words of the speaker. In the question, you have mentioned a sentence which is already direct in nature and thus its conversion to direct speech is not possible.

This is an incorrect question.

The only change I would suggest in the question is the use of quotation marks.
