Uthman ibn Affan quotes:

Allah the Exalted loves him who forgoes worldly life, the Angels love him who rejects the vices, and the Muslims love him who gives up greediness in respect of the Muslims.

No one conceals something in his heart, but Allah causes it to be seen on his face or in a slip of the tongue.

Absorption in worldly affairs breeds darkness in the heart, and absorption in the affairs of the next world enkindles light in the heart

Worrying about the dunya is a darkness in the heart, while worrying about akhirah is a light in the heart.

Had our hearts been pure, we would never tire with the Dhikr of Allaah.

Three worldly things have been made dear to me: feeding the hungry, clothing the naked and reading the Qur'an.

Acquire wisdom from the story of those who have already passed.

If the hearts are pure, they will never have enough from reciting Allah's words (the Qur'an).

Enjoin what is good and forbid what is evil before the worst amongst you are given authority over you and then when even the best of you make dua against them, their duas will not be accepted.

If anyone stumbles then he must repent. If anyone errs then he must repent. And no one must insist on (the path of) destruction. If anyone insists on tyranny then he is far away from the path

If our hearts were truly pure, we would never have our fill of the words of your Lord

It is sufficient for you that the one who envies you is distressed at the time of your joy.

Take note of the fact that I am a follower (of the religion) and not an innovator.
