Overall meaning : the God-fearing who obey Allah’s commands and avoid what He forbids will dwell amidst vast gardens and running springs, joyously receiving the great blessings Allah will bestow on them in Paradise.
They will be in such bliss because they did good works in the life of the world; they slept but a small part of the night—spending the greater part of it in prayer; they would ask their Lord for forgiveness before dawn and would give a due share of their possessions to those who ask for help and the destitute who do not ask for anything.
