Dawud said, "Be like a merciful father towards the orphan. Know that
you will reap as you sow. How ugly poverty is after wealth! More than that:
how ugly is misguidance after guidance! When you make a promise to your friend,
fulfil your promise. If you do not, it will bring about enmity between you
and him. Seek refuge in Allah from a companion who, when you mention something
to him, does not help you and who does not remind you when you forget."
