A man's measure is his will.
Ali Ibn Abi Talib
A brother is like gold and a friend is like diamond. If gold cracks you can melt it and make it just like it was before. If a diamond cracks, it can never be like it was before.
Do not be too hard, lest you be broken; do not be too soft, lest you be squeezed.
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 be glorified, has placed hidden secrets, which they are forbidden to reveal.
Abstinence from sins is better than seeking help afterwards.
