Ibnul Qayyim رحمه الله
... it is to do whatever PLEASES Allaah سُبحانه وتعالى ...!
…They say that the best worship is to do
what will please Allaah سُبحانه وتعالى
at every time in accordance with what that particular time calls for.
So, the best acts of worship during
the time of Jihad is Jihad, even if this leads to abandoning certain
rituals such as night prayer, fasting, etc. In fact, this applies even if you
are to not pray a complete obligatory prayer as you would in times of safety
and calm.
And the best thing to do when
you have a guest, for example, is to see to his rights as a guest and to
preoccupy yourself with that instead of the recommended rituals you would
usually engage in at the time.
Such is also the case in fulfilling the
rights of your wife and family.
The best thing to do during the
early morning hours is to be preoccupied with prayer, Qur'aan,
supplication, remembrance of Allaah, and asking His Forgiveness.
