The sin which makes you sad and repentant is more liked by Allah than the good deed which turns you arrogant.

Greed is permanent slavery

Do not take someone's silence as his pride, perhaps he is busy fighting with his self.

A girl is a good deed and a boy is a bounty. Good deeds are rewarded while people are held accountable for bounties.

Do not share the knowledge with which you have been blessed with everyone in general, as you do with some people in particular; and know that there are some men in whom Allah, may He he glorified, has placed hidden secrets, which they are forbidden to reveal.

Lead such a life, that, when you die, the people may mourn you, and while you are alive they long for your company.

Whoever educates himself and improves his own morals & character is superior to the man who tries to teach & train others.
