Causes:
 
"But he who talks improperly, thoughtlessly, and not to the point, or utters abuse, talks nonsense, mocks, or discusses the qualities and defects of others' wives, or stares at the wives or daughters ('ayal) of other people, or falls in love with another's wife, or if it be a woman falls in love with a man who is not lawful to her to see — then, — may we implore the help of God from God's wrath! — all that man in the course of the whole of his life earned by prayers (namaz) and worship ('ibadat), all that he earned by pious actions, — all this will be given up, thrown to the wind of nonexistence, all will be lost! ... God the All-High will be displeased and dissatisfied. His prosperity will be ruined, and he himself will have to live by begging, in distress, misery, and despair. Both in this world and the hereafter he will be surrounded by darkness and obscurity, he will have to suffer in the hereafter the punishment of Hell, being burnt in eternal fire."
 

(Pir Pandiyat-i Jawanmardi, pp.6-7)

Remedies:
 
"The (real) believer is one whose word is true, who does not use bad language, does not slander or abuse (anybody), and does not do any one what he does not want to be done to himself."
 
"The (real) believer is one who is pious and sincere by heart, whose actions are not crooked, who has no designs on the property or wives of others, and who abstains from stretching out his hand for what is unlawful to him."
