What is the ruling on what the questioner did by unintentionally repeating a word that contains an insult to time or fate, after having repented from repeating songs that included that?

Whoever recites poetry containing unlawful elements, such as disbelief (kufr) or obscenity, is blameworthy. However, it does not amount to disbelief unless he affirms what he hears, believes in it, or is pleased with it. So, if you repeat some words that involve cursing time without believing in it, you are not considered to be cursing it. Nevertheless, you should avoid repeating such things, as relating them playfully, without denouncing them, is blameworthy. What a person says in a state of astonishment and bewilderment is not held against him, and similarly, relating it for academic purposes, not for jest, imitation, or amusement.
