It is true that we do not know exactly, as to which night is the Night of Power (Lailatul-Qadr), but this should not prevent us from praying and requesting for its comprehension, of course to identify as to which night is the Night of Power, it has been narrated that from the beginning of the Holy Month till the night of twenty third, Surah-44, al-Dukhan should be recited one hundred times or Surah-97, al-Qadr should be recited one thousand times every night.
Also, for better comprehension of the Night of Power (Lailatul Qadr), there is a narration in the book of Iqbal, whose authenticity although is questionable, nevertheless, because of the profound importance of the Night of Power (Lailatul-Qadr), to act in accordance with the tradition, assuming its authenticity as correct would be reasonable. The summary of the tradition is as follows:
Ibne Abbas has quoted from the Holy Prophet [s]:
"I teach you a prayer (salat) that if you performed it, you will see the Night of Power (Lailatul Qadr) every night, twenty times or even more in the following manner:
Four rak'at prayer with one salutation (Salam), in every rak'at one time Surah al-Fatihah (the Opening), three times Surah al-Kafirun (the Disbelievers) and three times Surah al-Ikhlas (the Sincerity). After finishing salutation, recite the tasbeeh (praise) of Fatimah al-Zahra [a] thirteen times, and recite the invocation Astaghfirullah (Oh Allah, Forgive me) thirteen times.
The aim of the narration is not explicitly clear for us, and perhaps what is meant by seeing twenty times or even more Night of Power could be, that for someone like this, there is a reward, which is equivalent to the pleasure of seeing the twenty Nights of Power or even more. For example, it has been narrated that the reward of recital of one praise (tasbeeh) is greater than the Prophet Solomon's [a] Kingdom. But the interpretation of those who think that the reward of this prayer (salat) is equivalent to the reward of worship and night-vigil of twenty or even more Nights of Power (Lailatul-Qadr) is not correct.
