Some people have the disease of criticising all the time. They forget the good about others and only mention their faults. They are like flies that avoid the good and pure places and land on the bad and wounds. This is because of the evil within the self and the spoiled nature.

Don’t depend too much on anyone in this world because even your own shadow leaves you when you are in darkness.

The disease that knowledge brings is arrogance, and the disease that worship brings is showing off

As for the people of Tasawwuf, they affirm the love of Allah, and this is more evident among them than all other issues....the affirmation of the love of Allah is well-known in the speech of their [old] and recent masters, just as it is affirmed in the Holy Qur'an and the Sunnah and in agreement of the ways of the early generation (Salaf)

If you correct your hidden deeds subsequently, Allaah will correct your outward deeds.

When people help one another in sin and transgression, they finish by hating each other.

Make tawba not just for sins you've committed, but also for obligations you haven't fulfilled.
