AhsanAllahu ilaykum For laylatul qadr: Does a person get reward of 83+ years if he utilizes every second of it from maghrib to fajr- or is it attained just by doing some worship even if a person sleeps the rest of it? Or just by tarawih with imam? How is the reward divided in the time?

Ustadh AbdulAziz al-Haqqan

Praying night prayer with the imam is considered as qiyam for a whole night. As for what Allah accepts and considers on He knows may Allah reward you.
