He who carries out one good deed acquires one advocate in his own behalf, and he who commits one transgression acquires one accuser against himself. Repentance and good works are like a shield against calamity.
Man has three friends on whose company he relies. First, wealth which goes with him only while good fortune lasts. Second, his relatives; they go only as far as the grave, leave him there. The third friend, his good deeds, go with him beyond the grave.
Never expose yourself unnecessarily to danger; a miracle may not save you...and if it does, it will be deducted from your share of luck or merit.
Whoever destroys a single life is as guilty as though he had destroyed the entire world; and whoever rescues a single life earns as much merit as though he had rescued the entire world.
