What is the ruling on performing Tahajjud on Laylat al-Qadr exclusively, without the other nights?

The Night of Decree is better than a thousand months, and whoever stands in prayer during it with faith and hope for reward, will have his past sins forgiven. Scholars have differed in determining the exact night of Laylat al-Qadr, and the most accurate opinions suggest it is one of the odd nights in the last ten days of Ramadan. The wisdom behind concealing it is to encourage the Muslim to exert effort in worship throughout all these ten nights. It is not possible to definitively pinpoint a specific night as Laylat al-Qadr, for knowledge of it was lifted after two men disputed. Therefore, a Muslim should not single out one night for worship during these ten days. The Prophet, peace and blessings be upon him, used to strive hard in worship throughout all the last ten days.
