"O Messenger of Allah!
I want to go out and fight and
I have come to ask your advice."
He said: "Do you have a mother?"
He said: "Yes." He said:
"Then stay with her,
for Paradise is
beneath her feet."

Book 25, Hadith 20

Abu Huraira reported: I said, “What is
Paradise built from?” The Messenger of
Allah, peace and blessings be upon him,
said, “Bricks of silver and gold, its
mortar is musk of strong fragrance, its
pebbles are pearls and rubies, and its
soil is saffron. Whoever enters it will
enjoy bliss without despair and eternity
without death. Their clothes will not
fade, nor will their youth expire.”

Allah the Exalted and Glorious, said: I
have prepared for My pious servants
which no eye has ever seen, and no ear
has ever heard, and no human heart has
ever experienced but it is testified by the
Book of Allah. He then recited:" No soul
knows what comfort has been concealed
from them, as a reward for what they did".
