Question

Rahim said" I walk for two hours everyday" (change the mode of narration)

Answer 1

Rahim said that he walked for two hours everyday.

Answer 2

Indirect/Reported Speech refers to a dialogue being said to a third person/reporting what happened to a third person.

Example: Tara said,"I am going to the mall." (Direct)

               Tara said that she was going to the mall. (Indirect)

In the above example, when writing in indirect/reported form, the sentence changes according to its tense. Also, modifications regarding certain words like 'this' changes to 'that', 'tomorrow' changes to 'the next day', 'will' changes to 'would', 'you' changes to 'I', 'yesterday' changes to 'the previous day' and many other words will have to be made.
