In this last days of holy month Ramadan there is a lot of telling about Night of Power.
My question is how do we concurred (know) that "Laylat Al Qadr" occurs every Ramadan.
As you can see below the verse 44:4 (in bold) refers to the Laylat al-Qadr:
By the clear Book,
إِنَّا أَنزَلْنَاهُ فِي لَيْلَةٍ مُّبَارَكَةٍ ۚ إِنَّا كُنَّا مُنذِرِينَ
Indeed, We sent it down during a blessed night. Indeed, We were to warn [mankind].
فِيهَا يُفْرَقُ كُلُّ أَمْرٍ حَكِيمٍ
On that night is made distinct every precise matter
And because of the present tense of the word "is made distinct( يُفْرَقُ )", we believe that the Laylat al-Qadr do occur every year.
We know from many ahadith that laylatul al qadr happends during ramdan:
Sahih Bukhari : Volume 3, Book 32 "Taraweeh", Number 238
Narrated ‘Ibn Abbas (Radi Allah Anha): The Allah’s Messenger (sal-allahu- alleihi-wasallam ) said: “Look for the Night of Qadr in the last ten nights of Ramazan on the night when nine or seven or five nights remain out of the last ten nights of the Ramazan.”
As we know, ramdan occurs every hijri year, and if laylatul qadar hapends in ramdan, then it must occur every hijri year too.
Although we may not know the exact date of laylatul qadr we know for sure that it happens every year.
