Whatever is not done by the permission of Allah will not happen, and what is not done for the sake of Allah will not benefit or remain.
Ibn TaymiyyahGuidance is not attained except with knowledge and correct direction is not attained except with patience.
Ibn TaymiyyahIt is strange that a person may find it easy to protect himself from: eating Haraam, oppression and injustice, adultery, theft, drinking khamr (alcoholic drinks), and from unlawful looking, but it is hard for him to restrain the movement of his tongue. How often do we see people who are very cautious about falling into shameful deeds or injustice, but their tongue lashes against the living and the dead and they don't mind it?
