Praise be to
Allaah.
The
Muslim who is able to earn a living must strive to earn that which will
keep him and those under his guardianship, such as his wife and children,
from having to beg, and to earn what he needs to spend on their maintenance.
If he manages to do that, then if he spends the rest of his time, whether
during the night or the day, in worshipping Allaah by praying, fasting,
reading Qur’aan, that is better. There is no specific time for worship
in general, but yes, praying qiyaam at night is better than praying
during the day. This does not mean that there is no reward for praying
naafil prayers during the day. He should start by doing that which is
obligatory, whether the obligation is towards Allaah or towards His
creation, then he can use the rest of his time for doing that which
is mustahabb, and if he indulges in some permissible activities for
the purpose of relaxation and recreation, that is OK.
