In Surah Al-Qadr (Chapter 97) of the Holy Quran, Allah said:
1. We have indeed revealed this (Message) in the Night of Power.
2. And what will explain to thee what the Night of Power is?
3. The Night of Power is better than a thousand Months.
4. Therein come down the angels and the Spirit by Allah's permission, on every errand:
5. Peace!... This until the rise of Morn!
Based on the consensus of the Ulamaks, Lailatul Qadr will occur on one night in the holy month of Ramadhan.
Good deeds performed during the Night of Power (Lailatul Qadr) would be rewarded equivalent to deeds performed over a period of a thousand months.
The whole world will be calm during the occurrence of Lailatul Qadr.
However, a night time at one place would mean a daytime at another.
Hence, in my opinion, the Night of Power will continue throughout a period of at least 24 hours, covering the night time of every inch of the globe. Of course, a person on the ground would only experience his own period of night time, and be blessed with the deeds that he performed during his own period of Lailatul Qadr.
Allah has indicated that the Peace would prevail throughout the occurrence of Lailatul Qadr. I believe that the earth would become very calm during the occurrence of Lailatul Qadr.
And I believe that there would not be any earthquakes throughout Lailatul Qadr, as an indication that the earth is in peace and is celebrating the Night of Power.
Jurublog’s Prescene 6 (a.k.a. the Lailatul Qadr Hypothesis) states that:
“During the Holy Month of Ramadhan, there will be a period of at least 24 hours in which there will be no occurrence of earthquakes throughout the entire world. That period will indicate the Night of Power or Lailatul Qadr. For avoidance of doubt, the period of calmness would cover an entire night in the Holy City of Makkah (i.e. from sunset until dawn).”
