Allāh ﷻ hid the Night of Power by His ﷻ wisdom so that people would not worship only on that night and leave the others. Our Prophet ﷺ said it is mostly in the last ten days of Ramaḍān, especially the odd nights, though it may be on any night of the year. Therefore the elders said: know every night as Laylatu l-Qadr. Whoever prays every night will find this blessed night.
