Contemplation and remembering
Contemplation and reflection, together, lead to a third central Qur'anic term, "remembering," and its derivatives.
-The Almighty says(what mean):
([This is] a blessed Book which We have revealed to you, [O Muhammad], that they might reflect upon its verses and that those of understanding would be reminded.)
Quran (38:29).
- and said (what means):
( And We have certainly made the Qur'an easy for remembrance, so is there any who will remember?)
Quran (54:17)
Contemplation is realized through looking at the Qur'anic verses. While the "reflection" is realized through thinking of the universal signs. This is mostly, perhaps I found this in that sense. They have a dialectical relationship, because one leads to the other.
The contemplation of the Quran leads you to think about the universe, and thinking about the universe takes you back to the Quran. Both of them reminds the heart of the Hereafter.
