"See you not that Allah drives the clouds gently
then join them together
then makes them into a heap of layers
and you see the rain comes forth
from within them."
- The Qur'an, An-Nur, 43
O son, be sure to observe the universe and your own self and contemplate on His words.
"We will show them Our Signs in the Universe and in their own selves until it becomes manifest to them that this (the Qur'an) is the truth." (Al Fusilat: 53)
