IMAM HUSSAIN (A.S) says:
People are slaves to the world, and as long as they live favorable and comfortable lives, they are loyal to religious principles. However, at hard times, the times of trials, true religious people are scarce.
HOLY PROPHET MOHAMMED (SAW) says:
Appreciate five things before five others: Your Youth before your Old age, Your Health before your illness, Your Wealth before your Poverty, Your Spare Time before your hard work and Your Life before Death.
