Be Pious is a characterist of the true muslim and many more to the sufis, must the heart and acts are in truth love (it is Piety, are no Passion as the hipocraties think that passion is love) and care your duties from Allah CC to your live. do not leave the path when the difficulties are there.
Remember the sample from our Beloved prophet (saw): he never left a creature or way, when the difficulties came, because of the true slave knows that : in the dificulties the slave find the Creator.
 Is very common for the hipocraties , when the wishes are not  contemplated, they go to find others ways,
with arrogance and/or fear, leaving the others (companions, soldiers, partners) for to take a new one, what can make more easy to take the wishes.

what they do not know?
They do not know the knowledge truth. They do not know that are going to a prision of the soul , of the mind. And the acts in easy way (as fugitive ) , is cowardice by devil caring their hearts , blinding the eyes of the heart for to have a real observation of the facts, and, also to leave the real responsabilities in this live.

By observing the things created by Allahccs, make a continued reflection, above all, verify that the "'Seriousness is required in your actions, to all those who are near or far from you.'s More, for those who need of you and you certainly is the one most in need of it (to get the blessings of Allahcc working in the mission. The minimum what you will understand, if your heart is oppened to AllahCC, is taht from the facts wrot by Allah CC in difficulties relationship for to get the midle for to survive, then you got knowledge from Allahcc about Allahcc. So never left those Allahcc wrote for be by side in this travel , in all stations).
