[…] Those who patiently persevere will truly receive a reward without measure!” (39:10)
Sorrowing and worrying in times of trouble and trial are not sins, even weeping in sudden shock is not a sin, nor is it an act of impatience. Impatience is to criticise Allah and to lament and complain.
Patience is to hold firm to one’s faith in Allah even when his whole world is crumbling into ruins and heart is heavy with grief and eyes are brimming with tears. It is this patience for which has been promised boundless reward.
p/s Even when the world is not on your side, when you have ALLAH in your heart, you have it all. Have Faith.
p/p/s: to treat a patient, requires a lifetime patience. ^_^
