The Messenger of God, may God’s prayers and peace be upon him, said, “O people, do not give wisdom to anyone other than those who deserve it, lest you oppress it. Do not withhold wisdom from those who deserve it, lest you oppress them. Do not punish an oppressor, lest your bounty is nullified. Do not show off to people, lest your work is nullified. And do not withhold what exists, lest your goodness diminish. O people. Indeed, three things are a matter whose soundness is evident, so follow it.” And a matter whose wrongdoing is evident, so avoid it. And a matter whose error is disputed over you, return it to God, O people. Except that I inform you of two matters whose provision is light and whose reward is great. The likes of which God has never found: silence and good manners .
