A revelation from the Most Gracious, Most Merciful;- 41:2
Hadith of the day
Seek Knowledge and adorn it with forbearance and dignity. Be humble to those whom you teach and to those from whom you learn. Don't be tyrannical in your teaching conduct, for you will forfeit that to which you are entitled to (the reward) on account of it.
