Do for this life as if you live forever, do for the afterlife as if you die tomorrow.
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 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.
I was not created to be occupied by eating delicious foods like tied up cattle.
He who busies himself with things other than improvement of his own self becomes perplexed in darkness and entangled in ruin. His evil spirits immerse him deep in vices and make his bad actions seem handsome.
