Sayings of Imam Musa Kazim (as):

Imam Musa Kazim (as) said: "If there is a walnut in your hand and
people say that it is a pearl, their saying will not benefit you in
any way when you know that it is actually a walnut. And if there is a
pearl in your hand and people say that it is a walnut, their saying
will not harm you in any way when you know that it is actually a
pearl."
Imam Musa Kazim (as) said: "Indeed cultivation and growth takes shape
in a soft, even land and not in a rocky (barren) land. Likewise,
wisdom grows and develops in a humble heart and not in a proud, vain
and arrogant heart."
Imam Musa Kazim (as) said: "Always say the right thing although it may
lead to your loss." "It is better to be defeated on principle than to
win on lies." Arthur Calwell
