Translation:

3. The Night of Power is better than a thousand Months.

Notes (Tafseer)

6218. "A thousand" must be taken in an indefinite sense; as denoting a very long period of time. Cf. notes 3632 and 3634 to xxxii. 4-5, and n. 5678 to lxx. 4. This does not refer to our ideas of time, but to "timeless Time". One moment of enlightenment under Allah's Light is better than thousands of months or years of animal life, and such a moment converts the night of darkness into a period of spiritual glory.
