There is no goodness in people who don't give advice, and there is no goodness in people who don't like to be advised

I looked at all friends, and did not find a better friend than safeguarding the tongue. I thought about all dresses, but did not find a better dress than piety. I thought about all types of wealth, but did not find a better wealth than contentment in little. I thought of all types of good deeds, but did not find a better deed than offering good advice. I looked at all types of sustenance, but did not find a better sustenance than patience.

He who does now know evil will fall into it.

As long as you are pure of heart, you speak the truth.

He who does not live in the way of his beliefs starts to believe in the way he lives.

When you see that any scholar loves the world, then his scholarship is in doubt.
