Allah Almighty hides the knowledge of Laylatul Qadr so that every Muslim would strive in the last ten days of Ramadan, and more especially on the odd (i.e 21st ,23rd,25th,27th,29th) nights of this period. The Prophet ﷺ said: “Search for Laylatul Qadr on the odd nights of the last ten days of the month of Ramadan.” [ Agreed upon.] Some of the scholars, after studying several ahadith concerning Laylatul Qadr, said that it alternates among the odd nights.
