in his will to his son Hasan (AS) said, 'And if you find a needy person who is deprived who can carry your provision for you until the Day of Judgment and who will pay you back tomorrow when you need it, then seize the opportunity and let him hold this provision for you. Increase in giving provisions to the poor if you are able to, for you might look for them and not find them. Seize the opportunity to lend someone when you yourself are free from need so that he may repay you in your time of difficulty.'
