Ibn Al-Qayyim (rahimahullaah) said in al-Fawaa’id:
Allaah the Exalted said:
Verily, therein is indeed a reminder for him who has a heart or gives ear
while he is heedful. (Qaaf 50:37)
When you desire benefit from the Qur’an, then bring your heart together
during its recitation, listen heedfully and have the presence of the one who is
being addressed and spoken to, since it is a speech from Him, the Sublime, to
you, upon the tongue of His Messenger (sallallaahu alaihi wasallam).
This is because the best and most complete effectis suspended between the
following:
1. that which produces the required effect,
2. a place which receives this effect,
3. the condition which is necessary to receive such an effect and
4. the absence of that which prevents this effect from being obtained.
This verse has included all of the above with the most concise and clear of
wording, which is most direct in expounding the intended meaning.
His speech: (Verily, therein is indeed a reminder...) is an indication
of what has preceded from the beginning of Surah Qaaf to the present and this
constitutes that which produces the desired effect.
And His speech: (...for him who has a heart...) this is the place
which receives the effect and what is desired by it is: a living heart which
understands from Allaah, just as the Exalted has said:
It is but a Reminder and a Manifest, Clear Qur’an, that he (Muhammad) may
give warning to him who is alive (i.e. the healthy and live heart of the
believer.) (Yaa Seen 36:69-70)
And His speech: (...or who gives ear...) the one who directs his
listening and the perceptive faculty of his hearing to what is being said to
him, and this is the condition of benefitting and receiving the desired effect
from the words (that one hears).
And His speech: (...while he is heedful) meaning his heart is present
and witnessing, not absent and unmindful.
Ibn Qutaibah said: "Listen to the Book of Allaah, while your heart and
understanding are present, not while you are unmindful and forgetful."
And this is an indication of that which prevents the desired effect [from the
Book of Allaah] from being obtained and that is the forgetfulness and absence of
the heart from understanding what is being said to it, looking at it with care
and pondering slowly and carefully over it.
So when that which produces the effect and that is the Book of Allaah; a
place which receives the effect and that is the heart; the necessary condition,
which is paying attention; the absence of that which prevents the effect and
that is the hearts occupation and distraction away from the meaning of the
speech and its turning way to something else are all present, then the effect
will be obtained and realised and that is benefiting from the Qur’an and its
remembrance.
