This was probably referring to a particular night of a particular year.

It can also mean that it is more likely to be in that night but it is not a must.

Is this Hadith authentic “Narrated Mu’awiyah b. Abi Sufyan: The Prophet (pbuh) as saying: Lailat al-qadr is the twenty-seventh night (of Ramadan)”. If yes then what about the Hadith that says to search for the qadr last odd nights of last 10 days of Ramadan? Which one is correct?
